3, it is judged that whether URL to be visited is the URL that system has been cached, if so, illustrate that object corresponding for URL is not out of date, it is possible to the directly information of use local system buffer memory, now just need not carry out DNS acceleration process；If it is not, then perform step 4；
4, split URL, obtain domain name corresponding to this URL, and accelerate data message searches for this domain name at DNS, when searching, perform step 5；If not searching, process by normal browsing process.
Such as, when user is when browsing webpage, the connection of second level domain under Main Domain can be clicked, at this moment can get this second level domain and carry out the segmentation of URL, the map table in data message, the Main Domain after splitting, the lookup of the mapping relations of second level domain is accelerated according to above-mentioned DNS.
5, call DnsAccelerate () function, will wait that accelerating domain name is inserted in acceleration list.
This step particularly as follows:
DnsAccelerate () function call Windows system function QueueUserWorkItem (), notification queue daemon thread has domain name to wait to accelerate.
Queue daemon thread calls ParallelGetAddrInfoProc () function, performs following operation:
Call CreateSemaphore function, create semaphore；
Call:: QueueUserWorkItem (GetAddrInfoSysProc ， &pParseDataArray [index], 0), resolve domain name；The invoked procedure of this function is and accelerates to search for the process waiting to accelerate IP address corresponding to domain name in data message at DNS；
Waiting in all queues of task completes.
6, after domain name has been accelerated, get IP address information corresponding for URL to be visited, utilize this IP address information to conduct interviews process；
7, when user browses webpage corresponding for described URL, whether detection user's mouse hovers on the webpage currently browsed, and if so, obtains the webpage subregion DIV element that mouse-over position is corresponding；Wherein, mouse-over schematic diagram is as shown in Figure 3；
8, each URL in described DIV element is split, obtains domain name corresponding to each URL, and the domain name obtained is carried out duplicate removal process；
9, detection DNS accelerates whether comprise each domain name corresponding for described URL in data message, if comprising, then extracts the IP address information that each domain name is corresponding, and when user accesses the URL in described DIV element, directly utilize the IP address information of described extraction and conduct interviews process.
Mouse-over scheme is illustrated below:
The current location of detection mouse, and the URL link of the daughter element in the covered web page element of mouse.Such as mouse is currently located in<divclass=" nav2 ">
When the mouse-over<ahref=" http://mobile.sina.com.cn/ ">in above-mentioned DIV element goes up, the acceleration that the URL at this DIV can carry out DNS processes.
Hover over the URL which point is corresponding, this refers to<div...>...</div>in URL duplicate removal set, such as news.sina.com.cn；mil.news.sina.com.cn；finance.sina.com.cn；tech.sina.com.cn；mobile.sina.com.cn；digi.sina.com.cn.
