The method comprises that: a gateway receives a first connection request from a terminal; when the first connection request is judged to carry cache identification information, and the terminal does not request for network resources requested by the first connection request for the first time after login, the gateway transmits a second connection request from which the cache identification information is removed to a server providing the network resources; and the gateway receives the network resources transmitted according to the second connection request from the server, and forwards the received network resources to the terminal. By the method, the system and the device, the frequent transmission of the connection requests from the terminal is avoided, the load of network equipment is reduced, and the network resources are saved.
Description
Technical field
The present invention relates to networking technology area, espespecially a kind of for the network resource access control method between terminal and the webserver, system and device.
Background technology
In the conventional network resources system, terminal is by the server of accesses network resource provider, and obtaining Internet resources is service content.Caching mechanism basic in the network resource accession has been described in the HTTP1.1 agreement.Describe both sides by clear and definite message header identification field between terminal and server and whether support caching function.
Be illustrated in figure 1 in prior art terminal to the flow chart of the server request Internet resources of service provider.Wherein:
When terminal is accessed a certain Internet resources first, comprise the following steps: (1) terminal initiation connection request; (2) WAP (wireless access protocol) (Wireless Access Protocol, WAP) gateway forwards connection request is to server; (3) server issues Internet resources; (4) WAP gateway transmission network resource is to terminal.Wherein, when server issues Internet resources, the descriptor of Internet resources be can carry, recent renewal time (LastModified), valid expiration date (Expires) and other buffer control information (Cache Control) etc. comprised.
When terminal is repeatedly accessed a certain Internet resources, the process of each access comprises the following steps: (11) terminal initiation connection request, owing to not being to access for the first time, therefore in connection request, carries buffer memory sign (IfModified Since) field; (12) WAP gateway forwards connection request to server; (13) server issues response message notification terminal content and does not upgrade; (14) WAP gateway transmitted response message is to terminal.
That is to say, in prior art, terminal identifies by the identification field in the message header of connection request the terminal sent request and whether has caching function, and whether server also can identify this requested content and allow to be buffered.When allowing, the content that server generally will notification terminal be asked allows the term of validity be buffered, and after the term of validity, terminal can be initiated request again, in order to obtain new content.Terminal can be carried the relevant inquiring condition in connection request, whether the content of query caching is updated, and after this partial content of discovering server upgrades, the content after upgrading is offered to terminal, or this partial content of discovering server is not while upgrading, notification terminal does not need to upgrade.The purpose of this caching mechanism is with minimum information interaction amount, realizes effectively and timely the content information of buffer memory in new terminal more.
The implementation of above-mentioned network resource accession, for some terminals, the problem existed in realizing due to its caching mechanism (such as: cache contents destroyed grade or because setting causes its repetitive requests etc. before the deadline), in the time need to again obtaining asked Internet resources, can resend connection request, and owing to carrying the buffer memory identification field in connection request, make the server content of the Internet resources of asking of can having thought in terminal buffer memory, and can not re-issue asked network resource content to terminal.Terminal in the situation that can not regain Internet resources, can frequently send the connection request to the identical network resource.WAP gateway all can directly be transmitted to the server that Internet resources are provided accordingly by connection request at every turn, due to still before the deadline, therefore, server all can issue the unaltered information of network resource content to terminal at every turn, for example: issue code 304 (Not Modified) at every turn, do not change with this network resource content of notification terminal.And the content of asked Internet resources can not sent to user terminal, cause terminal can't normally show this partial content.
Due to terminal frequent behavior that sends connection request in the Internet resources term of validity, cause server to receive a large amount of invalidation request, cause very large service processing pressure to the network equipment.
Especially when having the same Internet resources of a plurality of terminal request of caching function, WAP gateway can send to the request of each terminal ISP's server one by one.When situation about frequently sending request when above-mentioned terminal occurs, because WAP gateway does not possess caching function, but directly carry out the information forwarding, may cause still a large amount of forwardings of the Internet resources connection request in the buffer memory term of validity, cause the waste of Internet resources.

In the network resource access control method that the embodiment of the present invention provides, its flow process as shown in Figure 2, comprises the following steps:
Step S11: the connection request (the first connection request) that the gateway receiving terminal sends.
Preferably, above-mentioned gateway is WAP gateway, can certainly be other gateway.
Step S12: whether the connection request that the gateway judgement receives carries the buffer memory sign.
When described connection request carries the buffer memory sign, execution step S14.When not carrying, execution step S13.
Step S13: the normal flow according to buffer memory Internet resources is not processed connection request.
Step S14: whether this asks the Internet resources of asking in above-mentioned connection request after reaching the standard grade first to judge this terminal.
When determining terminal, not while after this is reached the standard grade, accessing the Internet resources of asking first, execution step S15; Otherwise execution step S17.
Step S15: the connection request (the second connection request) after gateway transmission removal buffer memory identification information is given the server that Internet resources are provided.
Step S16: server issues Internet resources to terminal by gateway.
Server issues Internet resources to terminal according to the connection request after removal buffer memory identification information.Thereby make terminal can get in time required Internet resources, avoid the frequent transmission of connection request.
Preferably, said method also comprises:
Step S17: gateway is according to the whether effective result of determination of the Internet resources of the judgement terminal institute buffer memory got, transmission information, to terminal, comprising: the Internet resources after the renewal that the response message that the network resource content that the transmission sign is asked does not upgrade or forwarding server issue are to terminal.
When determining that terminal is the Internet resources that after this is reached the standard grade, access is asked first, by gateway by the Internet resources of the judgement terminal institute buffer memory that gets whether effectively result of determination send to terminal, and after the renewal when the Internet resources of judging terminal institute buffer memory are invalid, server issued, Internet resources send to terminal.
Above-mentioned by gateway by the Internet resources of the terminal institute buffer memory that gets whether effectively result of determination send to terminal, and Internet resources send to terminal after judging when invalid the renewal that server is issued.Comprise two kinds of situations, a kind of is to judge that by gateway whether the Internet resources of terminal institute buffer memory are effective, and a kind of is to judge that by server whether the Internet resources of terminal institute buffer memory are effective.Describe (gateway all take WAP gateway describe as example) in the following embodiments below by two specific embodiments.
Embodiment mono-:
The network resource access control method that the embodiment of the present invention provides, during the terminal access network resource, if it is the Internet resources of asking first after this is reached the standard grade that WAP gateway is determined terminal, connection request is transmitted to server, judged that by server whether the Internet resources of terminal buffers are effective.The method flow process as shown in Figure 3, performs step as follows:
Step S101: terminal sends connection request to WAP gateway.
When terminal needs the accesses network resource, can send connection request, generally can indicate the address information of the Internet resources that will access in connection request.Generally can pass through URL(uniform resource locator) (Uniform/UniversalResource Locator, URL; Or title web page address) carry out the address information of marked network resource.
The connection request that step S102:WAP gateway receiving terminal sends.
Step S103: in the connection request that judgement receives, whether carry the buffer memory identification information.
After the WAP terminal receives connection request, it is resolved, and whether judgement wherein carries the buffer memory identification information, for example: the If-Modified-Since field, think and carried the buffer memory identification information when this field is arranged, otherwise think and do not carry the buffer memory identification information.
If, execution step S105; Otherwise, execution step S104.
Step S104: the normal flow according to buffer memory Internet resources is not processed connection request, by server, issues Internet resources to terminal.
If do not carry the buffer memory sign, terminal does not possess the buffer memory ability or this Internet resources do not allow to be buffered, according to the normal flow under caching situation not, process, WAP gateway is transmitted to connection request the server that these Internet resources are provided, and server issues Internet resources to terminal by WAP gateway.
Step S105: judge this terminal be whether after this is reached the standard grade first request receiving to connection request in the Internet resources of asking.
WAP gateway is generally according to the address information of the Internet resources of the institute's request access comprised in connection request, URL for example, this reaches the standard grade whether access first this network address afterwards the judgement terminal, determines whether terminal accesses the corresponding Internet resources in this network address first.
If, execution step S108; Otherwise, execution step S106.
Connection request after step S106:WAP gateway transmission removal buffer memory identification information is to corresponding server.
Be WAP gateway when determining this terminal and not being the Internet resources of asking first after this is reached the standard grade, the buffer memory identification information in the connection request received removed, for example: remove the If-Modifled-Since field in connection request.After Reseal, the connection request after removal buffer memory identification information is sent to the server that Internet resources are provided.Thereby can issue smoothly Internet resources to terminal after making server receive connection request, ensure that terminal can get correct network resource content information, reduce follow-up unnecessary repetitive requests.
Simultaneously, WAP gateway records the Internet resources that this connection request relates to and the terminal iidentification of accessing these Internet resources, shows that this terminal asked the Internet resources that relate in connection request.
Step S107: server issues Internet resources to terminal.
Server issues the terminal of Internet resources to the request Internet resources according to the connection request after removal buffer memory identification information.
Step S108:WAP gateway directly sends to connection request the server of the Internet resources that provide asked.
WAP gateway will receive before connection request sends to the server that Internet resources are provided, and record the cache information of the Internet resources that terminal asks.
Step S109: server judges that whether the Internet resources of terminal buffers are effective.
If, execution step S110; Otherwise, execution step S111.
Server, according to the descriptor that receives connection request and these Internet resources, judges that whether the Internet resources of terminal buffers are effective.Update time, valid expiration date and other buffer control information that wherein, in descriptor, can comprise these Internet resources.
Server, according to update time and/or the valid expiration date of the Internet resources of asking that carry in the connection request by receiving, compares with update time and/or valid expiration date in descriptor, determines that whether the Internet resources of terminal buffers are effective.When corresponding identical, confirm that the Internet resources of terminal buffers are effective with update time in descriptor and/or valid expiration date in above-mentioned connection request, otherwise invalid.
Step S110: server returns to the network resource content that the response message notification terminal asks and does not upgrade.
Server returns to response message by WAP gateway to the terminal that sends connection request, carries the state code of content in response message, and the Internet resources of asking in order to marking terminal are effectively, the renewal of not modifying.
Step S111: server issues asked Internet resources to terminal.
When the Internet resources of server judgement terminal buffers are invalid, the Internet resources after upgrading can be handed down to the terminal sent request; Simultaneously, the cache information recorded in WAP gateway delete step S108.

The Internet resources that step S125:WAP gateway issues server are transmitted to the terminal sent request.
Step S126: judge whether this terminal is the network address that after this is reached the standard grade, access is asked first.
If, execution step S130; Otherwise, execution step S127.
Connection request after step S127:WAP gateway transmission removal buffer memory identification information is to server.
Be that WAP gateway removes the If-Modified-Since field in the connection request received, connection request sent to the server that Internet resources are provided.Simultaneously, WAP gateway records the network address that this connection request relates to and the terminal iidentification of accessing this network address, shows that this terminal asked the network address related in connection request.
Preferably, WAP gateway also can not remove the If-Modifled-Since field, and has lost efficacy by the information of revising other field identification terminal buffers, needs server to re-issue Internet resources corresponding to this network address.
Step S128: server issues Internet resources to WAP gateway.
Server issues Internet resources that the network address http in connection request: // 61.135.154.43/info/disengag.gif is corresponding to the terminal sent request.
Carry the descriptor of Internet resources simultaneously, for example: issue time T hu, 17Apr 2008 08:28:11GMT, update time Thu, 17 Apr 2008 06:00:00 GMT, valid expiration date Thu, 17 Apr 200810:00:00 GMT etc.
The Internet resources that step S129:WAP gateway issues terminal are transmitted to the terminal sent request.
WAP gateway is the descriptor of transmission network resource simultaneously.
Step S130:WAP gateway directly sends to connection request the server of the Internet resources that provide asked.
Step S131: server judges that whether the Internet resources of terminal buffers are effective.
If, execution step S132; Otherwise, execution step S134.
Server will receive the valid expiration date Tue in connection request, and the valid expiration date in the descriptor of 04Sep 2007 02:01:22 GMT and local these Internet resources that arrange compares, and determines that whether these Internet resources of terminal buffers are effective.Can certainly be according to update time or the judgement of other buffer control information.
Step S132: server returns to response message to WAP gateway.
The network resource content that step S133:WAP gateway forwards response message notification terminal is asked does not upgrade.
(for example: field 304), the Internet resources that marking terminal is asked do not upgrade to carry not Modified in the response message forwarded.
When term of validity existence is upgraded, can carry in order to inform the new valid expiration date of these Internet resources of terminal simultaneously.
Step S134: server issues Internet resources to WAP gateway.
Server issues Internet resources that the network address http in connection request: // 61.135.154.43/info/disengag.gif is corresponding to the terminal sent request.
Carry the descriptor of Internet resources simultaneously, for example: issue time T hu, 17Apr 2008 08:28:11GMT, update time Thu, 17Apr 2008 06:00:00 GMT, valid expiration date Thu, 17 Apr 200810:00:00 GMT etc.
The Internet resources that step 135:WAP gateway issues terminal are transmitted to the terminal sent request.
WAP gateway is the descriptor of transmission network resource simultaneously.
Embodiment bis-
The network resource access control method that the embodiment of the present invention provides, during the terminal access network resource, if it is the Internet resources of asking first after this is reached the standard grade that WAP gateway is determined terminal, further judges that whether the information of terminal buffers is effective, and carry out subsequent step according to judged result.The method flow process as shown in Figure 4, performs step as follows:
