Embodiment three
The method that the embodiment of the invention provides a kind of browser to carry out domain name mapping, this method are the further elaborations in detail to embodiment one and embodiment two said methods, specifically comprise:
One, DNS expedited data information generates step;
When server side generates, comprising:
1) collects Main Domain, and utilize the Main Domain configuration Main Domain pond of collecting;
Wherein, the mode of collecting Main Domain configuration Main Domain pond include but not limited to for: receive each Main Domain that user side reports, and/or, obtain the whole network focus domain-name information, utilize visit capacity before N position Main Domain dispose said Main Domain pond; Said N is a positive integer.
2) in the Main Domain pond, choose each Main Domain one by one, intercepting system function getaddrinfo () obtains the corresponding secondary subdomain name of corresponding Main Domain, and the IP address information of Main Domain and each secondary subdomain name.
In this step, the system function of interception is getaddrinfo (const char*nodename, const char*service, const struct addrinfo*hints, a struct addrinfo**result) function.
Wherein, nodename: domain name to be resolved (ASCII fromat); Service: the ANSI character string that comprises service name or port; Hints: Netz ocket reminder-data structure indicates procotol family, socket type, agreement etc.; Result: resolve the return data structure, be used for the data that saved system resolves.
If the getaddrinfo function returns success, the variable that is pointed to by the result parameter so has been received in a pointer, and its points to is the addrinfo structure chained list that is together in series by wherein ai_next member.The situation that can cause returning a plurality of addrinfo structures has following two:
1, have a plurality ofly with the address of nodename parameter association, be applicable to that so each address of institute's request address bunch all returns the structure of a correspondence.
2, service parameter service specified is supported a plurality of socket types, and each socket type all possibly returned the structure of a correspondence so, specifically depends on the ai_socktype member of hints structure.
The embodiment of the invention; Before interception getaddrinfo function, distribute a hints structure earlier, filling in the field that needs after its zero clearing; Tackle getaddrinfo () function again; Obtain corresponding Main Domain corresponding secondary subdomain name and the said Main Domain socket address structure corresponding,, obtain the Main Domain IP address information corresponding with each secondary subdomain name again according to the socket address structure with each secondary subdomain name.

Wherein, The DNS expedited data information of the DNS expedited data information of calling for downloading at server side; Perhaps; Be the DNS expedited data information of the server side active push that receives, and/or the DNS expedited data information of calling is the DNS expedited data information that the URL of browser statistic of user accessing obtains.
2, when browser address bar changed, promptly the user had initiated the access request to certain URL, resolved this access request, obtained URL to be visited;
Wherein, address field changes and is meant that the user is in the address field input or by the automatic recommended URL of address field.
3, judge that whether URL to be visited is the URL that crosses of buffer memory of system, if, explain that the corresponding object of URL is not out of date, can directly use the information of local system buffer memory, just need not carry out the DNS acceleration this moment and handle; If not, execution in step 4 then;
4, cut apart URL, obtain the corresponding domain name of this URL, and in DNS expedited data information, search for this domain name, when searching, execution in step 5; If do not search, by the normal access flow processing.
For example; As user during at browsing page, can click the connection of the second level domain under the Main Domain, at this moment can get access to this second level domain and carry out cutting apart of URL; According to the map in above-mentioned DNS expedited data information table, the searching of the Main Domain after cutting apart, the mapping relations of second level domain.
5, call DnsAccelerate () function, domain name to be quickened is inserted in the acceleration tabulation.
This step is specially:
DnsAccelerate () function call Windows system function QueueUserWorkItem (), notification queue daemon thread have domain name to wait to quicken.
The formation daemon thread calls ParallelGetAddrInfoProc () function, carries out operation as follows:
Call the CreateSemaphore function, create semaphore;
Call:: QueueUserWorkItem (GetAddrInfoSysProc ， &pParseDataArray [index], 0), resolve domain name; This function calls process is and in DNS expedited data information, searches for the process of waiting to quicken the corresponding IP address of domain name;
The task in all formations of waiting for is accomplished.
6, after domain name quicken to be accomplished, get access to the corresponding IP address information of URL to be visited, utilize the processing that conducts interviews of this IP address information;
7, when the user browses the webpage of said URL correspondence, detect user's mouse and whether on the webpage of current browsing, hover, if obtain the corresponding webpage subregion DIV element in mouse-over position; Wherein, the mouse-over sketch map is as shown in Figure 4;
8, each URL in the said DIV element is cut apart, obtain the corresponding domain name of each URL, and the domain name that obtains is gone heavily to handle;
9; Detect whether comprise the corresponding domain name of each said URL in the DNS expedited data information,, then extract the corresponding IP address information of each domain name if comprise; And during the URL in the said DIV element of user capture, directly utilize the processing that conducts interviews of the IP address information of said extraction.
