Description
Technical field
The present invention relates to Internet technical field more particularly to a kind of exterior chain url resource transfer method and devices.
Background technique
Most of current internet is the IPV4 using 32 bit address.The IP address space deficiency of IPV4 agreement constrains mutually
The development of networking.Internet address distributor gear (IANA) is 2 months in 2011 by last 2 of its IPV4 address space section
"/8 " group of addresses dispenses.It is " idle in this event flag landing pit registration body (RIR) IP available V4 address space
The termination in pond ", China Internet development will be by no available restriction in the address Pv4.It is not only taken at present in China or even world IPV6
Inexorable trend is had become for IPV4.
However, current most of mature applications mainly use IPV4 network, upgrade to IPV6 agreement experience from IPV4 agreement
The relatively deficient and larger workload of needs: application provider need to largely modify the code of existing system, relevant to IP address
Logical code is all revised as compatible IPV4/IPV6 agreement, and the hardware nets environment upgradings such as server place computer room is needed to support
IPV6.Entire work has fast implemented high risk and high investment.With the urgent promotion that country upgrades the IPV6 network rebuilding,
A kind of method that IPV4 application quickly can be moved into IPV6 network is needed, so that also accessible IPV4 is abundant by IPV6 user
Internet resources, the website IPV4 can first using some transition schemes, compatible IPV6 user and IPV4 user be accessed simultaneously, industry master
There is three types of technology route: double-stack technology, tunneling technique, translation technology.Wherein, 1 double-stack technology: double-stack technology requires to be related to
Web site traffic interaction types of applications system, the network equipment, Operation Support System hardware and software device simultaneously run IPV4 and
Two sets of protocol stacks of IPV6, can handle IPV4 and IPV6 data packet simultaneously.Using double stack routes to IPV6 evolution, website and answer
Re-written code is generally required with system, comprising: network communication socket, API, URL, storage organization etc.；2 tunneling techniques: pass through
Tunneling technique upgrades website and application system, it is desirable that website and user install the tunnel IPV6 software respectively, user application with
IPV4 agreement (private address) and website application communication, and IPV4 message is encapsulated into the tunnel IPV6, network transmission is penetrated, it is typical
Technology has Veno, Dslite, GRE etc.；3 translation technologies: translation technology is to dispose IP agreement between IPV6 user and the website IPV4
Conversion equipment establishes the mapping relations of address and port between IPV6/IPV4, to realize that it is mutual that transparent IPV6 and IPV4 exchange visits
It is logical.Typical technology has NAT64, IVI, seven layers of reversed proxy server.
Although these three technologies have their own advantages, all have the shortcomings that one it is shared, i.e., can not solve the problems, such as " skylight ".Institute
Meaning " skylight " problem refers to, if the website A content page of a support IPV6 agreement, refers to one and do not support IPV6 agreement
Website B picture or other resources when, when IPV6 client access website A content when, use the website dns resolution A
The address IPV6, and the response page based on IPV6 agreement and A Website server interaction acquirement A, when IPV6 client analyzes the website A
When page load needs to go to take the picture or other resources of the website B, the address IPV6 of the same first dns resolution B of meeting, due to B net
It stands and does not complete IPV6 transformation, the address IPV6 can not be resolved at this time or access B web failure using IPV6 address protocol.
IPV6 client obtains the website B picture or resource failure, and the clients such as browser is caused to occur when showing A Website page
The window of blank, referred to as " skylight ".In above-mentioned " skylight " examples of problems, for the originating website A, the net that includes in A
It stands the picture of B or other resources url is known as exterior chain url.That is exterior chain url refers to the url of the domain name chain of non-content provider site.
As it can be seen that " skylight " problem has seriously affected true customer experience.
For " skylight " problem, following disadvantage is individually present in three of the above technology: 1, double-stack technology is to website and application
It unites more demanding, server and upgrading network equipment may be involved, investment is larger and the transformation period is longer, is that one kind is drilled for a long time
Into technology, be relatively more suitable for framework and the relatively simple website IPV6 upgrading of business in a short time, large-scale website is often mutual
It mutually quotes, one-side upgrading is inevitably present " skylight " problem；2, using tunneling technique, website only needs to increase newly
One IPV6 tunnel server, but the corresponding tunnel the IPV6 software of user installation is needed simultaneously, universality and convenience have office
Limit, and can not solve the problems, such as " skylight ", so being suitable for the application environment of C/S model or the field of the mountable terminal of user
Scape, but unsuitable large scale deployment；3, the NAT64 in translation technology and IVI belongs to network layer translation technology, only at IP layers and transmits
Layer converts IPV4/IPV6 message, can not identify application layer content, so can not solve the problems, such as " skylight ".
Based on above-mentioned technology there are the problem of, need a kind of method for solving the problems, such as " skylight " that can be safer at present.

The embodiment of the present invention is applied to exterior chain url resource transfer service system, including IPV6 client, dns server, double
Stack proxy server, source station server, the website exterior chain url are deployed with exterior chain url resource transfer agency on double stack proxy servers
Device.Wherein, IPV6 client be using the client of IPV6 address machine, include browser or APP software etc., can be to website
Initiate the HTTP request based on IPV6 agreement in content service end.Double stack proxy servers be possess simultaneously the address IPV6 and IPV4 and
The machine of protocol handling capability is deployed among client and source station server-side and plays the part of proxy role, installs seven layer proxy services
Software can be communicated with the both ends of agency using the IP agreement that opposite end is supported.Source station server is web site contents server,
Content service response is provided, supported IP address agreement and double stack agency service end communications can be used.
Exterior chain url resource transfer system is applied to IPV6 client and accesses the originating website A, includes the website exterior chain url in A
The scene of resource (including picture or other resources), it is the website www.aa.com, request that IPV6 client, which accesses the originating website A,
The http://www.aa.com/ page contains client loading page in response contents and needs the exterior chain url for continuing request to be
http://bbb.bb.com/1.jpg.Wherein, exterior chain website bbb.bb.com only supports IPV4 agreement.
Specifically, request response interactive process are as follows:
1, IPV6 client access the http://www.aa.com/ page, the dns resolution address www.aa.com IPV6 to pair
On stack proxy server, IPV6 client sends request http to double stack proxy servers by IPV6 agreement: //
www.aa.com/。
2, after double stack proxy servers receive request, then the server for requesting go back to the place www.aa.com source station is forwarded.
3, the source station www.aa.com server is rung after receiving pair request of stack agency services to the return of double stack proxy servers
Answer the content http://www.aa.com/ page.
4, after double stack proxy servers receive the response of the source station www.aa.com server, whether analysis response page content
Connection string comprising exterior chain resource, such as http://bbb.bb.com/1.jpg, then the response for modifying source station server is
Wherein yy.xx is the domain name that can parse the address IPV6 to http://bbb.bb.zz.yy.xx/1.jpg, can be general domain name
Aa.com or other domain names.Zz can be the code name character string of com or com, facilitate the true url processing of sequential reduction.
5, after double stack proxy servers rewrite exterior chain resource, revised page response content is sent to IPV6 client
End.
6, IPV6 client receives the http://www.aa.com/ page response that double stack agencies send, and analyzes displayed page
Also need load exterior chain resource http://bbb.bb.zz.yy.xx/1.jpg.
7, IPV6 client is to the address IPV6 of dns server request analysis bbb.bb.zz.yy.xx, due to general domain name
.yy.xx IPV6 address resolution is supported, and parsing address is double stack proxy servers place, IPV6 client is acted on behalf of to double stacks and taken
Device be engaged in based on the transmission http://bbb.bb.zz.yy.xx/1.jpg request of IPV6 agreement.
8, double stack proxy servers receive http://bbb.bb.zz.yy.xx/1.jpg request, identify zz.yy.xx character
The exterior chain url of string, removes yy.xx information, and reduction zz is com, preparation request exterior chain resource http://bbb.bb.com/
1.jpg。
9, it when double stack proxy server preparation request http://bbb.bb.com/1.jpg, is first parsed to dns server
The source station address IPV4 of bbb.bb.com, the response by IPV4 agreement to the source station bbb.bb.com request exterior chain resource, and
After obtaining response, IPV6 client is given by IPV6 protocol forward exterior chain resource response.
10, IPV6 client obtains normal load exterior chain resource after exterior chain resource response (including picture or other moneys
Source), without " skylight " problem.
Based on the same inventive concept, the embodiment of the present invention provides a kind of exterior chain url resource transfer method, is applied to double stack generations
Server is managed, exterior chain url resource transfer proxy server is deployed on double stack proxy servers, refering to what is shown in Fig. 1, the present invention is implemented
A kind of exterior chain url resource transfer method that example provides, includes the following steps:
Firstly, executing step S101: the exterior chain url resource transfer service that starting is disposed on double stack proxy servers.
Specifically, starting on double stack proxy servers to realize that exterior chain url resource transfer proxy server can be identified
Exterior chain url resource transfer services corresponding response contents, if the connection string comprising exterior chain resource, if provided comprising exterior chain
The connection string in source then starts the exterior chain url resource transfer service disposed on double stack proxy servers.
Specifically, specifically comprise the following steps S1011~S1013 in step S101:
Execute step S1011: detection receives the response page content that source station server is sent.
Specifically, the response page content sent to the source station server that double stack proxy servers receive is monitored.
It should be noted that IPV6 client accesses the http://www.aa.com/ page, dns resolution www.aa.com
On the address IPV6 to double stack proxy servers, IPV6 client sends HTTP request to double stack proxy servers by IPV6 agreement
http://www.aa.com/；After double stack proxy servers receive request, then request http://www.aa.com/ is forwarded to return
The server of source station where www.aa.com；It is backward that the source station www.aa.com server receives http://www.aa.com/ request
Double stack proxy server returning response contents.Therefore in the response page that double stack proxy servers can send source station server
Appearance is detected.
In embodiment, it after step S1011, needs to analyze response page by exterior chain url resource transfer proxy server
Content whether include unfinished IPV6 transformation exterior chain resource, specific implementation process is step S1012: analyzing the response page
Content whether include exterior chain resource connection string.
It should be noted that after double stack proxy servers receive the response of the source station www.aa.com server, analysis response
Whether content of pages includes that the connection string of exterior chain resource then modifies source station service such as http://bbb.bb.com/1.jpg
The response of device is that wherein yy.xx is the domain name that can parse the address IPV6 to http://bbb.bb.zz.yy.xx/1.jpg, can be with
For general domain name aa.com or other domain names.Zz can be the code name character string of com or com, facilitate the true url of sequential reduction
Processing.
In embodiment, after step S1012, if response page content includes not complete the exterior chain money of IPV6 transformation
Source then starts exterior chain url resource transfer service, otherwise the problem incompatible there is no network protocol, also just without starting exterior chain
Url resource transfer service, specific implementation process are step S1013: if analyzing the response page content includes exterior chain resource
Connection string then starts the exterior chain url resource transfer service disposed on double stack proxy servers.
Specifically, after double stack proxy servers receive the response of the source station www.aa.com server, analysis response contents are
The no connection string comprising exterior chain resource, such as connection string comprising exterior chain resource, such as http://bbb.bb.com/
1.jpg then starts the exterior chain url resource transfer service disposed on double stack proxy servers.
In step S1013, start the exterior chain url resource transfer service disposed on double stack proxy servers, specifically
Include the following steps S10131~S10132:
Step S10131: rewriting the response page content with preset connection string rewriting rule, obtains

In specific implementation process, there are following several optional embodiments:
A1, by the exterior chain url resource transfer proxy server according to default rewriting rule, by including exterior chain domain-name information
Character string constructs special string, changes to the connection string for the exterior chain url resource for including in the response page content
It writes.
Specifically, being rewritten for the web site contents comprising exterior chain resource to exterior chain resource: with the website www.aa.com
For, the http://www.aa.com/ page is requested, client loading page is contained in response contents and needs to continue request
Exterior chain resource: http://bbb.bb.com/1.jpg.If the general domain name of aa.com completes IPV6 transformation, and bbb.bb.com is not
IPV6 transformation is completed, the skylight problem of http://www.aa.com/ page presentation will be caused, traditional solution skylight is asked thus
The scheme of topic is that exterior chain resource http://bbb.bb.com/1.jpg in the page is rewritten as http: //
Bbb.bb.com.yy.xx/1.jpg, wherein yy.xx is the code name referred to, yy.xx be one with can parsing IPV6
The domain name of location can be the aa.com or other domain names for having completed IPV6 transformation.Some modes may change .com into
Other characters, after rewriting exterior chain be http://bbb.bb.zz.yy.xx/1.jpg, for be isolated original exterior chain domain-name information and
New domain name yy.xx, convenient double stacks act on behalf of the real URL of sequential reduction exterior chain, and http://bbb.bb.com/1.jpg is simultaneously requested.
A2, by the exterior chain url resource transfer proxy server according to predetermined encryption rule, by including exterior chain domain-name information
Character string and privately owned code key building encrypted input word symbol string, and string is accorded with to the encrypted input word and carries out cryptographic calculation, added
Close operation result rewrites the connection string for the exterior chain url resource for including in the response page content.
Specifically, for example, exterior chain resource http://bbb.bb.com/1.jpg in the page is rewritten as http: //
The character string forms of AAAAAAAA.yy.xx/1.jpg, wherein yy.xx is that can parse double stack proxy server addresses
Domain name can be general domain name aa.com or other domain names.And AAAAAAAA is then the generation of a string of encrypted special strings
Refer to, the encrypted characters string create-rule are as follows: defeated by character string (the being assumed to be bbb.bb.com) building one comprising outer chain information
Enter character string, for the private cipher key that input character string and only double stack proxy servers are held, according to certain Encryption Algorithm into

Business has supported, and does not announce externally.Encrypted input word symbol string can also contain other than it may include exterior chain domain-name information comprising other
The character string of justice.Exterior chain resource url includes format sample belonging to domain name is unlimited after rewriting, or A-A-A-A-A-
The formats such as A.yy.xx, but generally containing can be according to the information of certain rule reduction actual encryption result string AAAAAAAA
With the domain name yy.xx information etc. that can be resolved to double stack proxy server addresses.
Cryptographic calculation result is cracked in order to prevent, and the character string comprising outer chain information can also be used to carry out hash fortune
It calculates, as described below:
A3, by the exterior chain url resource transfer proxy server according to predetermined encryption rule, by including exterior chain domain-name information
Character string and privately owned code key building encrypted input word symbol string, and string is accorded with to the encrypted input word and carries out cryptographic calculation, added
Close operation result rewrites the connection string for the exterior chain url resource for including in the response page content；And pass through
The exterior chain url resource transfer proxy server is according to default hash rule, by the character string comprising exterior chain domain-name information and privately owned word
Symbol string building hash input character string, and default hashing algorithm operation is carried out to hash input character string, it obtains signature and dissipates
Column operations is as a result, in conjunction with the company of the hash operations result to the exterior chain url resource for including in the response page content of signing
Character string is connect to be rewritten.
Specifically, for example, exterior chain resource http://bbb.bb.com/1.jpg in the page is rewritten as http: //
The string format of AAAAAAAABBBB.yy.xx/1.jpg, wherein yy.xx is the domain name that can parse the address IPV6, Ke Yiwei
General domain name aa.com or other domain names.And in the generation that AAAAAAAABBBB is then a string of encrypted special strings, refers to, should add
Close text string generation rule are as follows: an input character is constructed by the character string (being assumed to be bbb.bb.com) comprising outer chain information
String is encrypted for the private cipher key that input character string and only pair stack proxy server are held according to certain Encryption Algorithm
Operation, cryptographic calculation result are AAAAAAAA (not necessarily 8 characters), and cryptographic calculation result is cracked in order to prevent, may be used also
To use the character string comprising exterior chain domain-name information, splice the privately owned key character string that a double stack proxy servers are just held, structure
Input character string is built, a kind of hashing algorithm (such as MD5 value) is then selected to carry out hash operations, hashed result is extracted into fixed position
Character string BBBB splicing is after AAAAAAAA is gone here and there in encryption.The character string comprising exterior chain domain-name information is that any carrying can be released
Justice is the character string of bbb.bb.com domain name, can be bbb.bb.com.yy.xx or bbb--bb--com.yy.xx, bbb--
Bb--zz.yy.xx, bbb.bb.com, bbb--bb--com, bbb.bb.zz etc. but be not limited to above-mentioned character string)；It is described
BBBB hash character string not necessarily only refers to four characters, or the character of other digits in addition in the program, hashes character
It goes here and there nonessential scheme, encipherment scheme can also be used only, Hash scheme can be used as encipherment scheme supplement.The privately owned key word
Symbol string and private cipher key have been supported by double stack agency services, are not announced externally.Encryption or hash input character string are in addition to can
Comprising the character string of other meanings can also be included outside privately owned key, exterior chain domain-name information.Exterior chain resource url includes after rewriting
Format sample belonging to domain name is unlimited, or the formats such as A-A-A-A-A-A-B-B-B.yy.xx, but generally containing can be with
According to the information of certain rule reduction actual encryption result string AAAAAAAA or hashed result string BBBB and double stacks can be resolved to
Domain name yy.xx information of proxy server address etc..
In embodiment, it after step S10131, executes step S10132: passing through the exterior chain url resource transfer generation
It manages device and the revised page response content is transmitted to IPV6 client, so that the IPV6 client is initiated comprising described
When the exterior chain url call request of revised page response content, double stack proxy servers can be got from dns server
Address, then the exterior chain url call request is sent to double stack proxy servers, and make the exterior chain url resource transfer
Proxy server obtains the relevant information of the exterior chain url resource transfer service from the exterior chain url call request.
In specific implementation, there are following several optional implementations:
B1, the revised page response content is transmitted to by IPV6 by the exterior chain url resource transfer proxy server
Client, when so that the IPV6 client being initiated to include the exterior chain url call request of the revised page response content,
Double stack proxy server addresses can be got from dns server, then send the exterior chain to double stack proxy servers
Url call request, and it is described outer that the exterior chain url resource transfer proxy server is obtained from the exterior chain url call request
The exterior chain domain-name information of chain url resource transfer service.
For example, as shown in above-described embodiment A1, by the connection string http://bbb.bb.com/ of exterior chain resource
1.jpg, being revised as http://bbb.bb.zz.yy.xx/1.jpg, wherein yy.xx is the ground that can parse double stack proxy servers
Location information, bbb.bb are exterior chain url domain-name information.Zz can be the code name character string of com or com, facilitate sequential reduction true
Real url processing.
B2, the revised page response content is transmitted to by IPV6 by the exterior chain url resource transfer proxy server
Client, when so that the IPV6 client being initiated to include the exterior chain url call request of the revised page response content,
Double stack proxy server addresses can be got from dns server, then send the exterior chain to double stack proxy servers
Url call request, and it is described outer that the exterior chain url resource transfer proxy server is obtained from the exterior chain url call request
The exterior chain domain-name information and encryption information of chain url resource transfer service.
For example, as shown in above-described embodiment A2, exterior chain resource http://bbb.bb.com/1.jpg in the page is changed
The character string forms of http://AAAAAAAA.yy.xx/1.jpg are written as, wherein yy.xx is that can parse double stack proxy servers
The domain name of address can be general domain name aa.com or other domain names.And AAAAAAAA is then (false comprising exterior chain domain-name information
It is set as bbb.bb.com) encrypted special string, exterior chain url domain-name information can be parsed.
B3, the revised page response content is transmitted to by IPV6 by the exterior chain url resource transfer proxy server
Client, when so that the IPV6 client being initiated to include the exterior chain url call request of the revised page response content,
Double stack proxy server addresses can be got from dns server, then send the exterior chain to double stack proxy servers
Url call request, and it is described outer that the exterior chain url resource transfer proxy server is obtained from the exterior chain url call request
The exterior chain domain-name information and encryption information of chain url resource transfer service, and signature hash operations result.
For example, as shown in above-described embodiment A3, by the connection string http://bbb.bb.com/ of exterior chain resource
1.jpg replaces with the character string shaped like format http://AAAAAAAABBBB.yy.xx/1.jpg, and wherein yy.xx is that can parse
The address information of double stack proxy servers out can be general domain name aa.com or other domain names.And AAAAAAAABBBB is then
A string of encrypted special strings, AAAAAAAA are the encrypted characters string that can parse exterior chain url domain-name information.BBBB is packet
The character string of the hash operations result containing signature.
After step slol, it then executes step S102: calling proxy server to obtain the exterior chain by the exterior chain url
HTTP request of the url resource transfer service to IPV6 client for request call exterior chain url resource carries out revised exterior chain
Url call request.
For example, after double stack proxy servers rewrite exterior chain resource, revised page response content is sent to
IPV6 client；IPV6 client receives the http://www.aa.com/ page response that double stack agencies send, and analysis shows page
Face also needs load exterior chain resource http://bbb.bb.zz.yy.xx/1.jpg；IPV6 client is to dns server request analysis
The address IPV6 of bbb.bb.zz.yy.xx, since general domain name .yy.xx supports IPV6 address resolution, and parsing address is double stack generations
Where managing server, IPV6 client is based on IPV6 agreement to double stack proxy servers and sends http: //
Bbb.bb.zz.yy.xx/1.jpg request.
After step s 102, it then executes step S103: calling proxy server from the exterior chain by the exterior chain url
The address exterior chain url is determined in url call request.
It should be noted that for rewriting rule different in step S10131, the specific executive mode of step S103 also has
Institute is different.In above-mentioned A1 implementation, step S103 is specifically included: according to step from the exterior chain url call request
Preset rewriting rule, which carries out corresponding reduction, in 1013 can parse the address exterior chain url.
Specifically, double stack proxy servers receive http://bbb.bb.zz.yy.xx/1.jpg request, identification
The exterior chain url of zz.yy.xx character string removes yy.xx information, and reduction zz is com, preparation request exterior chain resource http: //
bbb.bb.com/1.jpg.Wherein zz effect is only to distinguish whether one of exterior chain resource identifies, and is then wanted if it is exterior chain resource
It removes yy.xx suffix and restores true url, otherwise do not have to removal yy.xx suffix reduction.It the use of zz code name can be original in yy.xx
When beginning website domain name aa.com, effectively distinguishing http://bbb.bb.zz.aa.com/1.jpg is that an exterior chain resource needs are gone
Except aa.com, rather than the resource of the website aa.com itself, if otherwise there is the non-exterior chain resource http of an aa.com itself: //
Ccc.cc.c.aa.com/ is also taken as exterior chain resource to remove aa.com, and forwarding will malfunction when requesting access to.
It should be noted that other websites http://ddd.dd.com/ for not supporting IPV6 agreement, (website can
Can be a malicious site) if having malicious user that website www.aa.com is transformed from IPV6 analyzes above-mentioned rewriting rule, mould
Intend improved exterior chain http://bbb.bb.zz.yy.xx/url format, directly inputs http in IPV6 client: //
Ddd.dd.zz.yy.xx/ accesses.At this time IPV6 client to dns server parsing yy.xx the address IPV6 to for
Www.aa.com carries out double stack proxy servers of IPV6 transformation, and double stack agency services are by the resource identification shaped like .zz.yy.xx
For exterior chain, then restores http://ddd.dd.com/ and then initiate request to source station where ddd.dd.com, accordingly even when
Ddd.dd.com does not complete IPV6 transformation, and malicious user can be used as springboard machine by above-mentioned double stack agencies in IPV6 client
Successful access is carried out to the website ddd.dd.com.Above-mentioned original double stack generations that IPV6 skylight problem is transformed for website www.aa.com
The springboard of any malicious access under IPV6 environment can be taken as because of the rewrite mechanism loophole of " skylight " problem by managing server
Machine not only wastes machine processing resource, but also is related to auxiliary sensitive message reference, it is clear that not to be happy to see.
Based on above-mentioned problem, in above-mentioned A2 implementation, a kind of solution " skylight " that can be safer is proposed
Problem method: a kind of rewriting rule system based on encryption, therefore in above-mentioned A2 implementation, step S103 is specifically included:
The encryption information that the exterior chain url resource transfer service is obtained by the exterior chain url resource transfer proxy server, according to described pre-
If encryption rule is decrypted, the address exterior chain url is restored.
Specifically, if step S1013 process does not include hashing algorithm operational character string BBBB, double stack proxy servers
Receive http://AAAAAAAA.yy.xx/1.jpg request, then directly according to decrypted result after, use fixed encryption to restore rule
It then restores http://bbb.bb.com/1.jpg to continue to request exterior chain resource, the exterior chain resource response forwarding that finally will acquire
Give IPV6 client.
Cryptographic calculation result is cracked in order to prevent, in above-mentioned A3 implementation, proposes a kind of solution that can be safer
Certainly " skylight " problem method: a kind of rewriting rule system based on encryption and signature, therefore it is directed to above-mentioned A3 implementation, step
S103 specifically comprises the following steps S1031~S1036:
Firstly, executing step S1031, obtaining the exterior chain url resource tune by the exterior chain url resource transfer proxy server
It with the encryption information of service, is decrypted according to the predetermined encryption rule, restores the address exterior chain url；
Step S1032, it is obtained in the exterior chain url call request by the exterior chain url resource transfer proxy server and includes
The exterior chain domain-name information and signature hash operations result；
Step S1033, by the exterior chain url resource transfer proxy server according to the exterior chain domain-name information and described default
Hash rule obtains the hash and inputs character string；
Step S1034, by the exterior chain url resource transfer proxy server, character string and described is inputted according to the hash
Default hashing algorithm operation obtains verification hash operations result；
Step S1035, by the exterior chain url call request resource transfer proxy server, by the verification hash operations knot
Fruit is compared with the signature hash operations result；
If step S1036, consistent, receive the exterior chain url call request, and solve from the exterior chain url call request
The address exterior chain url is precipitated；Otherwise, refuse the exterior chain url call request.
Specifically, double stack proxy servers receive if step S1013 process has comprising hashing algorithm operational character string BBBB
Http:// AAAAAAAABBBB.yy.xx/1.jpg request after then restoring decrypted result, is dissipated according to step S10131 is preset
Regular (only double stack proxy servers are held) is arranged, first obtains and splices hash input character string in step S10131, use step
The hashing algorithm of rapid S10131 calculates hashed result, and extraction step S10131 corresponds to the hashed result of digit, by the result
It is compared with BBBB character string, allows the request if consistent, and restoring exterior chain url is http://bbb.bb.com/
1.jpg continues to request exterior chain resource, and the exterior chain resource response that finally will acquire is transmitted to IPV6 client, if inconsistent, explanation
This is the malicious access that simulation " skylight " rewriting rule generates, and directly breaks off relations this and requests access to.It is advantageous that: malice is visited
Even if asking that user can simulate the url request of http://ZZZZZZZZZ.yy.xx/1.jpg format, but due to no privately owned close
Key value, double stack proxy servers can not be decrypted or decrypted result is not a domain name, and malicious access will will fail.If existing simultaneously
In the case where increasing hash operations, hashed value also can not be forged arbitrarily, by can not obtain double stack servers held it is privately owned
The digit for being originally inputted result after character string and hash and extracting of key, specific hashing algorithm and hash operations, malicious user
Can not puppet produce accurate hashed result signature value, access verification is unsuccessfully rejected.Double stack proxy servers are solved with this to be worked as
Make the springboard machine problem of malicious user.
After step s 103, it then executes step S104: calling proxy server to the exterior chain by the exterior chain url
The address url sends the HTTP call request, so that the exterior chain url resource transfer service is from double stack proxy servers
Call the exterior chain url resource.
Specifically, when double stack proxy server preparation request http://bbb.bb.com/1.jpg, first to dns server
The source station address IPV4 for parsing bbb.bb.com requests the response of exterior chain resource by IPV4 agreement to the source station bbb.bb.com,
And after obtaining response, IPV6 client is given by IPV6 protocol forward exterior chain resource response.
IPV6 client obtains normal load exterior chain picture after exterior chain resource response, without " skylight " problem.
In the specific implementation process, exterior chain url resource transfer method provided in an embodiment of the present invention can be applied to IPV6
Include the situation of exterior chain IPV4 site resource in client accession page, is below www.aa.com with IPV6 transformation website, outside
Chain resource url be http://bbb.bb.com/1.jpg, using the embodiment of the present invention provide exterior chain url resource transfer method into
Row exterior chain resource transfer is illustrated, and specific implementation step is as follows:
1, IPV6 client access the http://www.aa.com/ page, the dns resolution address www.aa.com IPV6 to pair
On stack proxy server, IPV6 client sends HTTP request http to double stack proxy servers by IPV6 agreement: //
www.aa.com/
2, after double stack proxy servers receive request, then request http://www.aa.com/ is forwarded to go back to www.aa.com institute
Server in source station.
3, the source station www.aa.com server returns after receiving http://www.aa.com/ request to double stack proxy servers
Return response contents
4, after double stack proxy servers receive the response of the source station www.aa.com server, analysis response contents whether include
The connection string of exterior chain resource then modifies the response contents of source station server such as http://bbb.bb.com/1.jpg, will
Http:// bbb.bb.com/1.jpg replaces with the character string shaped like format http://AAAAAAAABBBB.yy.xx/1.jpg,
Wherein yy.xx is the domain name that can parse the address IPV6, can be general domain name aa.com or other domain names, AAAAAAAABBBB
It is then a string of encrypted special strings.
5, revised http://www.aa.com/ page response is passed through IPV6 protocol forward by double stack proxy servers
Give IPV6 client.
6, IPV6 client receives the revised http://www.aa.com/ page response that double stack agencies send, IPV6
Client load response page when, discovery also need request http://AAAAAAAABBBB.yy.xx/1.jpg (as previously mentioned, this
Locate merely illustrative without limiting to this url format)
7, IPV6 client is to the address IPV6 of dns server request analysis domain name AAAAAAAABBBB.yy.xx, due to
General domain name .yy.xx supports IPV6 address resolution, and parsing address is double stack proxy server addresses, IPV6 client to
Double stack proxy servers are based on IPV6 agreement and send http://AAAAAAAABBBB.yy.xx/1.jpg (as previously mentioned, herein only
It is example without limiting to this url format).
8, double stack proxy servers receive http://AAAAAAAABBBB.yy.xx/1.jpg request, extract AAAAAAAA
Character string is simultaneously decrypted according to the private cipher key held, and the result bbb.bb.com after restoring decryption, detailed process is as follows:
If a, step 4 process does not include hashing algorithm operational character string BBBB, directly according to decrypted result after, use
Fixed also meta-rule restores http://bbb.bb.com/1.jpg and continues to request exterior chain resource, the exterior chain that finally will acquire
Resource response is transmitted to IPV6 client；
If b, step 4 process has comprising hashing algorithm operational character string BBBB, after restoring decrypted result, according to step
4 hash is regular (only double stack proxy servers are held), first obtains and splices hash input character string in step 4, use step
Rapid 4 hashing algorithm calculates hashed result, and the hashed result of the corresponding digit of extraction step 4, by the result and BBBB character
String is compared, and allows the request if consistent, and restoring exterior chain url is http://bbb.bb.com/1.jpg, continues to request
Exterior chain resource, the exterior chain resource response that finally will acquire is transmitted to IPV6 client, if inconsistent, illustrates that this is a simulation
The malicious access that " skylight " rewriting rule generates, directly refuses this and requests access to.
