Specific embodiment
Internet content distribution method provided in an embodiment of the present invention, device and system are not only built by introducing CDN SC The incidence relation between IDC and CDN has been found, CDN has more been realized and obtains the content that IDC needs to distribute online, also achieve simultaneously The automatic distributing of content.
Below in conjunction with Figure of description, preferred embodiment of the present invention will be described, it should be understood that described herein Preferred embodiment only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention, and in the absence of conflict, this hair The feature in embodiment and embodiment in bright can be combined with each other.
Embodiment one
As shown in Figure 1a, the flow diagram of the internet content distribution method provided for the embodiment of the present invention one, can be with The following steps are included:
S11, content distributing network service controller CDN SC obtain the log information of at least one content to be distributed, described Log information carries domain-name information.
Preferably, CDN SC (Content Delivery Network Service Controller, content delivery network Network service controller) can be obtained from DPI (Deep Packet Inspection, deep message detection) equipment at least one to Distribute the log information of content, wherein the log information DPI is collected from IDC.
When it is implemented, the content to be distributed that DPI equipment is acquired from IDC exists with IP packet format, wrapped in the IP packet The content contained is more, and more dispersed, includes domain-name information, browser model, source IP address, destination IP in IP packet information Address, port numbers, time etc..For the ease of subsequent progress content distribution and excessive garbage is avoided to occupy too many memory, Each IP packet need to be screened, such as be directed to each IP packet, using purpose IP address, language, port information and when Between it is equal content in IP packet is associated, filter out necessary information (such as domain-name information, port information and destination IP), It is possible thereby to filter out some IP packets without carrying out content distribution；Then the necessary information that will be filtered out according to budget rules A log information is generated, the log information includes domain-name information.
It is some it is not necessary that the domain-name information group in the IP packet can be extracted after carrying out the IP packet of content distribution filtering out It at the domain-name information list for not having caching value, is compared when obtaining domain-name information so as to next time, uses this operation can be with Improve the treatment effeciency of CDN SC.
At the same time it can also need to carry out the domain-name information column that the domain-name information composition of content distribution has caching value Table when avoiding obtain the domain-name information in the domain-name information list again next time, repeats the process of step S12, reduces CDN The treating capacity of SC.
S12, CDN SC determine that corresponding content distribution configuration strategy, the content distribution are matched according to domain name information It sets strategy and includes domain name server (DNS) service strategy.
Specifically, the DNS in the embodiment of the present invention one (Domain Name Service, domain name service) server can be with By two, such as operator DNS server (Local DNS) and network authorization dns server (Auth DNS).In order to distinguish this two A dns server, introduces DNS service strategy, and the DNS service strategy is awarded for subregion operator DNS server and network Weigh dns server.It specifically can be respectively the two dns servers setting identification information, and DNS service strategy carries the mark Domain-name information can be sent to the corresponding dns server of the identification information according to the identification information by information, CDN SC.
It, can be by when it is implemented, CDN SC determines corresponding content distribution configuration strategy according to domain name information It is executed according to method shown in Fig. 1 b, comprising the following steps:
S121, judge whether domain name information is newly-increased domain-name information, if so, thening follow the steps S122；Otherwise it holds Row step S125.
When it is implemented, CDN SC from DPI obtain each log information after, can be by the domain in the log information Name information is stored, while the content assignment configuration strategy process for generating the domain-name information can be also executed for domain-name information, Therefore, it is executed again for identical domain-name information in order to prevent and generates content distribution configuration strategy process, caused unnecessary The waste of process resource, CDN SC after obtaining domain-name information, by domain name information be stored in having in CDN SC All domain-name informations cached in the domain-name information list of value compare, if it is determined that go out the domain-name information in the domain In name information list, then it represents that the content distribution configuration strategy of the domain-name information has transmitted to CDN network, without sending out again It send, indicates that process terminates, is i.e. execution step S125；If it is determined that domain name information is in the domain-name information list, It then also needs all domain-name informations in domain name information and the pre-stored domain-name information list for not having caching value It is compared, if not finding domain name information in the domain-name information list for not having caching value, then it represents that should Domain-name information is newly-increased domain-name information, then the corresponding content assignment configuration of the domain-name information need to be determined according to step S122~S124 Strategy；If finding domain name information in the domain-name information list for not having caching value, then it represents that domain name letter Breath does not have caching value, without executing subsequent process.
Preferably, CDN SC can also store the original site element acquired from DPI, the content point for any domain-name information Hair configuration strategy and it is locally generated, store and safeguard user contracting data and other strategy.
S122, according to domain name information, judge whether the corresponding site element of domain name information meets to cache and sentence Broken strip part, if so, thening follow the steps S123；It is no to then follow the steps S126.
Specifically, the site element can be understood as the information on webpage, as text information, picture, video, script, Style sheet and JavaScript etc..
When it is implemented, can be determined by WebCache, such as domain-name information is configured in advance and is taken in WebCache It is engaged in white list, after obtaining domain-name information, if it is determined that the domain-name information obtained out is in WebCache service white list, then Determine that the corresponding site element satisfaction of the domain-name information can cache Rule of judgment, wherein in the WebCache service white list Domain-name information meet normal service whithin a period of time, and no user is complained.
S123, the content for needing to cache in the site element is determined.
When it is implemented, determining that the corresponding site element satisfaction of domain name information can cache judgement item in step S122 Part then it needs to be determined that the content for needing to cache in the site element, and generates content caching strategy and carries and configure in content distribution In strategy, CDN is then sent to by CDN SC, so as to CDN according to the cache policy in content distribution configuration strategy to the domain name Cacheable content is cached in the corresponding site element of information, fast implements content distribution after caching successfully.
S124, corresponding content distribution configuration strategy is generated according to domain name information and the content for needing to cache.
When it is implemented, the content distribution configuration strategy further includes at least one of following: domain-name information, content distribution side Formula, content caching strategy and content distribution priority.
Specifically, needs in the corresponding site element of the domain-name information that content caching strategy is determined according to step S123 The content of caching determines that the content for needing to cache can be text, picture or video etc., for example, CDN SC can remember The filename for the content that record needs to cache, is generated content caching strategy.It is needed it should be noted that CDN SC is only determined The content of caching, but the content not cached to the needs determined caches, and is cached by CDN network.
Further, not due to the significance level for the content for needing to cache in the different corresponding site elements of domain-name information It together, therefore can be according to perception degree of the user to the content for needing cache, in the corresponding site element of each domain-name information The corresponding content distribution priority of the curriculum offering for needing to cache one, high content its corresponding content distribution of perception degree are excellent First grade is higher.
Preferably, the content that can also be cached as needed determines that ways of distribution, such as some current events politics etc. can adopt It is pushed to user with the mode of active distribution, some other content for needing user to access then pushes by the way of passively distributing To user, the present invention provides two kinds of ways of distribution, needs to push corresponding contents according to user, improves user experience.
S125, process terminate.
Optionally, the case where DNS service strategy changes is likely to occur in the embodiment of the present invention, i.e., current Auth Dns server desires to participate in content distribution, then needs to send dispatch command to CDN SC, CDN SC upon receipt of the instructions, changes Become DNS service strategy, then updates content distribution configuration strategy, thus CDN SC also needs again to match updated content distribution It sets strategy and is sent to CDN network, and also need to send scheduling information, the i.e. domain-name information and CDN network to Auth dns server The IP address of middle CDN scheduling system.
S126, determining the site element, there is no the contents for needing to cache.
Preferably, purpose IP address is also carried in the log information, in order to which further screening is some without carrying out The log information of content distribution also wraps before executing step S121 and judging whether domain name information is newly-increased domain-name information It includes: determining the destination IP address in pre-stored IP address list.
When it is implemented, CDN SC has store function, operator's IP address can store, such as the IP of each operator of province Address forms the IP address network consisting authorization IP address list of operator's IP address list or network authorization, therefore, After obtaining log information, the purpose IP address in domain-name information can be compared with the IP address of storage, if it is determined that go out The purpose IP address has been stored in after operator's IP address list in advance in network authorization IP address list, then it represents that domain name letter Breath can execute subsequent step, otherwise indicate that the domain-name information is possible to as information unauthorized, without executing subsequent process.
By executing step S121~S126, CDN SC is judging domain name letter according to each domain-name information of acquisition After breath has caching value, respectively it generates corresponding content distribution configuration strategy, after being sent to CDN network, so that CDN Network can be configured automatically according to content distribution configuration strategy, change manual configuration procedures in the prior art, simultaneously also The incidence relation between IDC and CDN network is effectively established, so that the method that more business provide through the invention realizes content Quickly distribution.
S13, CDN SC send the content distribution configuration strategy to content distributing network CDN.
When it is implemented, CDN SC is after generating corresponding content distribution configuration strategy according to domain-name information, in order to realize Content distribution is also needed the content distribution configuration strategy being sent to CDN network, be held by CDN network according to content distribution policy The corresponding configuration process of row.
S14, CDN are configured according to the content distribution configuration strategy.
Since the content distribution configuration strategy includes domain-name information, and DNS service strategy corresponding with domain-name information, Content distribution mode, content caching strategy and content distribution priority, thus CDN network can be determined according to DNS service strategy This receives the dns server of user access request；CDN can also be according to the corresponding station of content caching access vector cache domain-name information The content for needing to cache in point element；And the content of the corresponding caching of each domain-name information is determined according to content distribution priority Priority orders, thus distribution when can according to priority orders realize content preferential transmission.
Preferably, since CDN SC is newly added equipment, in order to realize the content distribution configuration for receiving CDN SC and sending Strategy, CDN network need to be transformed the interface of itself, so that improved CDN interface supports service contracting and opens function Can, and each CDN service node can also will be distributed to inside content distribution configuration strategy that CDN SC is issued.
S15, CDN return to configuration result to CDN SC.
S16, CDN SC are according to the configuration result, if it is determined that going out the configuration result is configuration successful, then according to institute DNS service strategy is stated, sends scheduling information to the corresponding dns server of the DNS service strategy, the scheduling information includes domain The IP address of CDN scheduling system in name information and the CDN.
When it is implemented, CDN SC receives the configuration result that CDN is configured according to content distribution configuration strategy, if really Making the configuration result is configuration successful, then sends scheduling information to dns server.
Specifically, since dns server includes Local dns server and Auth dns server, so needing basis Scheduling information is sent to the corresponding dns server of DNS service strategy by DNS service strategy.
Further, dns server, can be by the domain-name information and CDN in scheduling information after receiving scheduling information The IP address of scheduling system is stored in domain name access list, so as to receive user request after, in domain name Access Column The domain-name information of user's access is searched in table.
By executing the process of step S11~S17, CDN SC complete transmission to the content distribution configuration strategy of CDN and Transmission to the scheduling information of dns server so that CDN is automatically performed configuration process, and effectively establish IDC, CDN and Correspondence between dns server extends the interests space of IDC.
CDN SC generate content distribution configuration strategy that content distribution configuration strategy and CDN are sent according to CDN SC into Row is with postponing, and after CDN SC sends scheduling information to dns server, content distribution process that CDN is executed with specific reference to Step S17~S112, explains it in detailed below:
S17, user terminal send user access request to dns server.
When it is implemented, user sends user's access to dns server and asks by clicking any link, such as xxx.com It asks, dns server parses domain-name information from the link after the user access request for receiving user's transmission.
The user access request is forwarded to the CDN according to the scheduling information by S18, dns server dispatches system The corresponding CDN of IP address dispatches system.
When it is implemented, DNS after the domain-name information for parsing the link, can be arranged in the domain name access being locally stored The domain-name information is searched in table, if found, system ip address is dispatched according to the corresponding CDN of the domain-name information, by user Access request is forwarded to the corresponding CDN scheduling system of CDN scheduling system ip address；If do not found, use is refused to respond Family request.
Preferably, user access request is being forwarded to the corresponding CDN scheduling of CDN scheduling system ip address by dns server When system, if the dns server is Local dns server, Forward plan is added in the link xxx.com of user Slightly, it is then sent to the corresponding CDN scheduling system of CDN scheduling system ip address；If the dns server is Auth DNS clothes Business device is then sent to the corresponding CDN scheduling system of CDN scheduling system ip address then by user.
S19, CDN dispatch system and determine CDN edge service node according to the user access request.Link xxx.com adds Enter CNAME strategy
When it is implemented, CDN, which dispatches system, determines edge service according to user access request and content distribution configuration strategy Node (optimal edge service node), is then sent to dns server for the IP address for the edge service node determined.
S110, CDN dispatch system and the IP address for the edge service node determined are sent to dns server.
The IP address for the edge service node determined is sent user terminal by S111, dns server.
S112, user terminal are after the IP address for receiving the edge service node, to the CDN Edge Server section Point initiates user access request, carries out content distribution according to the user access request by the CDN edge service node.
By executing step S17~S112, IDC, CDN SC, CDN and the direct correspondence of dns server are being established Afterwards, quick distribution of the CDN network to IDC content is not only realized, the service ability of CDN network has more been fully demonstrated, while Improve user experience.
The embodiment of the present invention one provide internet content distribution method, by increase newly CDN SC, and using CDN SC from DPI equipment obtains log information, and the log information is that DPI is collected from IDC, and then CDN SC is according to the log of acquisition Domain-name information in information determines the corresponding content distribution configuration strategy of the domain-name information, and the content distribution is configured plan It is slightly sent to CDN network, thereby establishes the incidence relation between IDC and CDN, IDC is realized and is cooperateed with the close of CDN, more IDC service business is expanded；After establishing aforementioned incidence relation, CDN network carries out phase according to the content distribution configuration strategy It should configure, after success to be configured, to CDN SC feedback configuration as a result, CDN SC is determining that the configuration result is configuration successful Afterwards, scheduling information is sent to dns server, the scheduling information includes the CDN scheduling system in domain-name information and CDN network IP address, so that dns server is after receiving user access request, if it is determined that go out the domain name in user access request The domain-name information that information is sent with the CDN SC received is consistent, then user access request is forwarded to the IP of CDN scheduling system The corresponding CDN in address dispatches system, so that CDN, which dispatches system, determines CDN edge service node according to the user access request, And the IP address for the CDN edge service node determined is fed back into dns server, dns server is receiving the edge CDN clothes It is engaged in after the IP address of node, the IP address of the CDN edge service node is sent to user terminal, so that user terminal passes through The IP address of this CDN edge service node sends user access request to CDN edge service node, by the CDN edge service Node realizes the quick distribution of content according to user access request, while also ensuring that IDC introduces content and CDN distributes content It is synchronous, the generation of mismatch problem caused by manually reporting and configuring is avoided, the service energy of CDN network has been given full play to Power improves user experience.

Refering to what is shown in Fig. 2, to judge whether the corresponding site element of domain name information meets in the embodiment of the present invention one The flow diagram of the first method of Rule of judgment can be cached, comprising the following steps:
S21, according to domain name information, respectively determine the corresponding site element of domain name information in include static state in Hold information and dynamic content information.
When it is implemented, having partial content that can occur according to the difference for the content that user usually accesses for any webpage Difference, such as Taobao's page, Taobao's client will record the access habits of user, for example women's dress or cosmetics are asked in user's A frequentation, Sportswear or shoes are asked in user's B frequentation, then Taobao's client can be respectively that they are presented not according to the access habits of user A and B With Taobao's page, but be user A presentation Taobao's page and be user's B program Taobao's page in have identical portion Point, such as the day cat pattern in Taobao's page, Tian Mao supermarket and some with the embedded picture or video being presented on Taobao's webpage Deng, these identical parts can cache, as static content information, and according to the purchasing habits of user in Taobao's page The content of display since Taobao's information of different user browsing is different, therefore does not have caching value, so this kind of content is referred to as Dynamic content information.It is possible thereby to determine the static content information and dynamic content information in site element according to the method described above.
Further, it is also possible to judge that the corresponding script information of the suffix name is according to the suffix name in site element including content No is dynamic content information, and such as some scripts are needed using Java Background scheduling program, and this kind of script is dynamic content letter Breath does not have caching value.
Preferably, some html text information have caching value, it may be determined that be static content information.
S22, ratio between the static content information and the dynamic content information is determined.
Due to the existing static content information of any webpage, and there is dynamic content information.If only had for each webpage Static content information is just cached, and will result in cached some nugatory contents in this way.Such as certain webpage, static state in Hold information and account for 10%, dynamic content information accounts for 90%, it can thus be appreciated that the webpage static content information is few, indicates that the webpage can be with It is some improper webpages, accessed probability is smaller, if the site element to the webpage caches, it will cause memories Unnecessary waste.
Therefore, in order to avoid the generation of above situation, the embodiment of the present invention is in the static content letter for determining site element After breath and dynamic content information, also needs further to judge, i.e., first determine the static content information and the dynamic content information Ratio, when it is implemented, the size of static content information can be measured and dynamic content information with the memory that it is occupied Size can be measured with its memory occupied, it is possible thereby to determine the ratio of static content information and dynamic content information Value, according to the ratio, you can get it, and ratio is bigger to represent that static content information is more, and the value of caching is also bigger；Conversely, ratio Smaller, dynamic content information is more, and the value of caching is also just smaller, and specifically determining that site element has according to step S23 can delay Sustainability.
S23, judge whether the ratio is greater than preset ratio threshold value, if so, thening follow the steps S24；Otherwise step is executed Rapid S25.
When it is implemented, if the ratio determined in step S22 is greater than preset ratio threshold value, then it represents that the domain-name information pair The site element satisfaction answered can cache Rule of judgment, that is, value can be cached by having, namely satisfaction can cache Rule of judgment；If small In or equal to then indicating that the corresponding site element of the domain-name information does not have caching value, the i.e. corresponding website of domain name information Element is unsatisfactory for that Rule of judgment can be cached.
S24, determine that the corresponding site element satisfaction of domain name information can cache Rule of judgment.
S25, determine that the corresponding site element of domain name information is unsatisfactory for that Rule of judgment can be cached.
It can determine that whether the corresponding site element of domain name information meets by executing step S21~S25 as a result, Rule of judgment can be cached, if it is satisfied, showing that there is the content that can cache value in the corresponding site element of the domain-name information, so Domain name information is stored in the domain-name information list with caching value afterwards；If conditions are not met, then showing that the domain name is believed It ceases in corresponding site element and does not have caching value, then can screen away the domain-name information, preferably, can be by the domain Name information is stored in the domain-name information list for not having caching value.In subsequent acquisition domain-name information, need to only delay having It deposits the domain-name information list of value and the domain-name information list without caching value searches whether the domain name comprising obtaining respectively Information effectively increases the treatment effeciency of CDN SC if executing corresponding operation comprising if.
Method two:
As shown in figure 3, can to judge whether the corresponding site element of domain name information meets in the embodiment of the present invention one Cache the flow diagram of the second method of Rule of judgment, comprising the following steps:
S31, according to domain name information, determine the port information for being used for transmission the corresponding site element of domain name information With http information.
When it is implemented, also carrying port information in the log information when obtaining log information according to step S11 With http information, and with domain-name information to corresponding.It is possible thereby to find the corresponding port of the domain-name information according to domain-name information Information and http information.
S32, according to the port information, judge whether the port information is the first default port information, if it is, Execute step S33；It is no to then follow the steps S35.
When it is implemented, the first default port information can be, but not limited to as " 80 " and " 8080 " port etc..
S33, judge whether the URL of the http information includes characteristic character, if so, thening follow the steps S37；Otherwise it holds Row step S34.
When it is implemented, URL (Uniform Resource Locator, uniform resource locator) characteristic character is correlation The key-strings of dynamic and interaction content do not provide local cache for such dynamic resource caching default and accelerate to service. CDN SC need in one URL characteristic character experience library of local maintenance, and can be increased newly, be deleted by front-end interface, being modified, It checks specific characteristic character, is used for daily caching operation maintenance.As characteristic character library may include api, bbs, login, password、upgrade、upload、post、weather、cnzz、push、passport、ntp、time、sdk、sex、 Click, google etc..
If it is determined that the URL includes features described above character, then show that the corresponding site element of current domain-name information is Private information does not have caching value.
S34, determine that the corresponding site element satisfaction of domain name information can cache Rule of judgment.
S35, according to the port information, judge whether the port information is the second default port information, if it is, Execute step S36；It is no to then follow the steps S37.
When it is implemented, the second default port information can be " 443 " port, robbed in order to avoid being buffered system It holds, part website can open 443 ports and be transmitted.
S36, judge whether the log information of the described second default port transmission is encrypted, if it is, executing Step S37；Otherwise, step S33 is executed.
When it is implemented, when being transmitted with " 443 " port, it is possible to there are encrypted transmissions, then need to judge with Whether the log information of " 443 " port transmission is encrypted and (such as monitors the handshaking information of SSL), if it is not, then indicating Practical and unused encryption mechanism is transmitted (the corresponding site element of the domain-name information is known as " false https resource "), then also Http judgement, i.e. execution step S33 need to be executed.It uses " 443 " port when being transmitted if detecting resource, uses encryption Transmission mode then determines that the corresponding site element of domain name information can not cache, that is, is unsatisfactory for that Rule of judgment can be cached, namely The affiliated domain name of resource is https domain name, is not cached.
S37, determine that the corresponding site element of domain name information is unsatisfactory for that Rule of judgment can be cached.
To sum up, it can judge whether the corresponding site element of domain name information meets by executing step S31~S37 Rule of judgment can be cached, after judging that satisfaction can cache Rule of judgment, that is, produces content distribution configuration strategy.
Preferably, deterministic process shown in Fig. 4 can also be performed in the present invention before executing step S33, may include with Lower step:
S41, the log information according to acquisition, determine http return code.
Specifically, before executing step S33, http return code can be determined according to the log information obtained from DPI.
Preferably, when user requests some URL for the first time, the return code of server end is 200, and content is that user asks The resource asked, while the time that the attribute of Last-Modified marks this file finally to be modified at period of service end, format such as: Last-Modified:Fri,12May 2006 18:53:33GMT.When user, which executes, requests above-mentioned URL for the second time, according to The regulation of http agreement, browser can transmit If-Modified-Since header to server, and file is after inquiring the time It is no to be modified, such as: 2006 18:53:33GMT of If-Modified-Since:Fri, 12May, if server end Resource does not change, then return code is 304 (Not Changed), and content is sky, and which offers a saving transmitted data amounts.Work as clothes When business device end code changes or restarts server, then resource is re-emitted, returned similar when being requested with first time.To Guarantee not repeat to issue resource to client, also guarantees that, when server changes, user can obtain newest resource.
S42, judge whether the return code is the first return code, if so, thening follow the steps S412 (i.e. step S33)； It is no to then follow the steps S42.
If return code is that the first return code such as " 304 " can then execute step S412 (i.e. step S33).
Preferably, if it is determined that return code is not the first return code, for example " 200 ", i.e. request or server for the first time End code changes or restarts, then also needs to judge http request mode, i.e. execution step S43.
S43, it determines http request mode, and judges whether the request method is GET mode, if it is, executing step Rapid S44；It is no to then follow the steps S414 (i.e. step S37).
When it is implemented, if request method is non-GET mode, directly execution step S414 determines the domain The corresponding site element of name information is unsatisfactory for that Rule of judgment can be cached；If it is determined that request method is GET mode, then it need to also be into One step is judged that i.e. execution S44 determines http Cache-Control Header (the general header field of http).
S44, Cache-Control in the general header field of http is determined.
When it is implemented, general header field includes request and the header field that response message is all supported, general header field includes Cache- Control、Connection、Date、Pragma、Transfer-Encoding、Upgrade、Via。
Specifically, communication two party is required all to support this extension the extension of general header field, it is general if there is what is do not supported Header field will generally handle the caching mechanism that the specified request of Cache-Control and response follow as entity header field.It is requesting Cache-Control is arranged in message or response message can't modify the caching process mistake in another message processing procedure Journey.Cache instruction when request includes no-cache, no-store, max-age, max-stale, min-fresh, only-if- Cached, the instruction in response message include public, private, no-cache, no-store, no-transform, must-ridate、proxy-ridate、max-age。
Determining that http request mode is difference of the GET according to response message in general header field, implementation procedure is also corresponding Difference, with specific reference to step S45, S48 and S49.
When it is implemented, the caching mechanism that Cache-Control header field is followed for specified request and response, disappears in request Setting Cache-Control can't modify the caching process process in another message processing procedure in breath or response message. Cache instruction when request includes no-cache, no-store, max-age, max-stale, min-fresh, only-if- Cached, the instruction in response message include public, private, no-cache, no-store, no-transform, must-ridate、proxy-ridate、max-age。
When it is implemented, Public instruction response can be cached by any buffer area.Private is indicated for single user's Response message all or in part cannot be shared caching process.This allows server only to describe to disappear when the part of user responds Breath, this response message are invalid for the request of other users.
No-cache instruction request or response message cannot cache；No-store is for preventing important information by unintentionally Publication, transmission will make to call request in request message and response message does not all use caching.
Max-age instruction client computer can receive the response of life cycle less at fixed time (in seconds).
S45, if it is determined that response message is " public " in Cache-Control, and determine Cache-Control Middle cache instruction " max-age is less than or equal to 0 ", thens follow the steps S46.
S46, judge that URL whether there is activity time Expires in http header field, if it is present executing step respectively The deterministic process of S411 and S412；If it does not exist, then executing step S47.
S47, judge to then follow the steps S412 if deposited with the presence or absence of eTag/Last-Modified in http header field；It is no Then follow the steps S414.
S48, if it is determined that response message is " public " in Cache-Control, and determine Cache-Control Middle cache instruction " max-age is greater than 0 ", thens follow the steps S412.
Specifically, max-age=600 (s), then it represents that from current time its, cache after 600s expired.
S49, if it is determined that in Cache-Control response message be " no-cache " or " no-store ", then execute Step S414.
When it is implemented, according to, for the explanation of no-cache and no-store, easily obtaining and disappearing if responded in step S44 Breath is no-cache or no-store, shows that the corresponding http information of the response message cannot be buffered.
S410, if it is determined that Expires be greater than Date, then follow the steps S412.
When it is implemented, Expires, which is used to indicate, caches expired absolute time, if having crossed specified that of Expires A time point indicates that caching is invalid, needs to re-request a newest.Date header field indicates the time that message is sent, time Descriptor format defined by rfc822.For example, Date:Mon, 31Dec200104:25:57GMT.The time of Date description indicates Greenwich mean time needs to know the time zone where user if being converted into local zone time.
Specifically, if it is determined that go out Expires and be greater than Date, then it represents that current time be less than Expires it is specified when Between, i.e., it is also not out of date, then follow the steps S412.
S411, if it is determined that Expires be less than or equal to Date, then follow the steps S414.
Specifically, if it is determined that go out Expires and be less than or equal to Date, then it represents that current time is more than Expires specified It is time, i.e., expired, then follow the steps S414.
S412, judge whether the URL of the http information includes characteristic character (i.e. step S33), if it is, executing step Rapid S414 (i.e. step S37)；It is no to then follow the steps S413 (i.e. step S34).
When it is implemented, the description of step S33 can be referred to, overlaps will not be repeated.
S413, determine that the corresponding site element satisfaction of domain name information can cache Rule of judgment.
S414, determine that the corresponding site element of domain name information is unsatisfactory for that Rule of judgment can be cached.
It should be noted that two kinds provided by Embodiment 2 of the present invention judge that the corresponding site element of domain name information is No satisfaction can cache Rule of judgment, when it is implemented, any judgment method can be executed, also may be performed simultaneously two kinds of judgements Method, it is possible thereby to which whether accurate judgement needs to cache the corresponding site element of domain name information, on this basis according to slow The content distribution configuration strategy for depositing analysis result and domain-name information generation is more accurate.
