In S301, terminal sends DNS query to name server by client and asked, and for the IP address to the domain name server query Web Server related to the webpage accessed, wherein DNS query request carries the host name of the Web Server.
In S302, name server returns to the DNS response messages responded to DNS query request to client, and the DNS response messages 7 carry the IP address of the Web server.
In S303, client initiates TCP SYN messages to Web server, begins setting up TCP connections.
In S304, Web Cache are obtained after the TCP SYN messages, obtain Web Server corresponding with the webpage that terminal expectation is accessed IP address, and the Web server that disguises oneself as is set up with client and is connected.
Alternatively, Web Cache are searched the IP address list locally preserved according to the IP address of the Web server, to determine whether the IP address list includes the IP address.If finding the IP address in the IP address list, then show that client requested resource may be deposited in local Slow, therefore delay is set up Web Cache and is connected with Web Server TCP, and flow proceeds to S306.
If not finding the IP address in the IP address list, Web Cache search local whether there is and are connected with the Web Server TCP having built up, if it is present, flow proceeds to S306, otherwise flow proceeds to S305.
In S305, the newly-built TCP with Web Server of Web Cache are connected, that is Web Cache are not it is determined that have the IP address in the IP address list locally preserved, and determine locally in the absence of when being connected with the Web Server TCP set up, be connected with the newly-built TCP of Web Server.
In S306, Web Cache disguise oneself as Web Server to client transmission TCP SYN ACK messages, and the TCP SYN ACK messages are used to confirm TCP SYN messages.
In S307, client sends TCP ACK messages to Web Cache, for showing that completion is set up in the TCP connections between client and Web Cache.Constraint is limited, and for example in embodiments of the present invention, S305 can be carried out before S306 or S307, can also simultaneously be carried out with S306 or S307.
In S308, client sends HTTP request message to Web Server, and just blunt text is equally obtained the HTTP request by Web Cache.
If in S304, determining that IP address is present in the IP address list locally preserved, or determine that locally presence is connected with the Web Server TCP having built up, then after Web Cache obtain the HTTP request, flow proceeds to S309;If in S304, it is determined that there is no the IP address in the IP address lists locally preserved, and determine local in the absence of when being connected with the Web Server TCP set up, then after Web Cache obtain the HTTP request, flow proceeds to S310.
In S309, Web Cache check locally whether have the web page resources that client is asked according to URL, if locally there is the web page resources, then flow proceeds to S313;Otherwise, Web Cache continue to search for local whether there is and are connected with the TCP that Web server has built up, if there is no the TCP connections having built up, then the newly-built TCP with Web Server of Web Cache are connected, and flow proceeds to S310, and if there is the TCP connections having built up, then flow is directly to S310.
In S310, Web Cache send the HTTP request message to Web Server to client and modified, and amended HTTP request message is sent into Web Server by the TCP connections.For example, the source IP address of the HTTP request message is Web Cache by terminal modifications by Web Cache.
In S311, Web Server send http response message to Web Cache, and the HTTP response messages are used for what the amended HTTP request message was responded, the http response message
The web page resources that carrying terminal is asked.
In S312, Web Cache decide whether that carrying out Slow to the web page resources deposits after the http response message is received according to local policy.If the web page resources need Slow to deposit, so Web Cache are while the web page resources are preserved, Web Server IP address is added in the IP address list, or the reference count of the IP address of the Web Server in the IP address list is updated.
The local policy can be the default policy of the strategy that operator configures on Web Cache or the setting of Web Cache manufacturers.For example, local policy configuration can be that a Slow deposits text and picture by operator, Slow does not deposit video；The default policy of Web Cache manufacturers is probably that a Slow deposits static Web page, and Slow does not deposit dynamic page etc..
In S313, Web Cache are created and are carried the HTTP response messages of the web page resources to what client was sent, and the http response message is returned into client.
In S314, client obtain after the web page resources with Web Cache disconnect TCP be connected.In S315, after connection time-out, Web Cache disconnect to be connected with Web Server TCP.Fig. 4 shows the schematic diagram for being used to access the method 400 of resource according to yet another embodiment of the invention, and this method 400 can be performed by agent apparatus.As shown in figure 4, this method 400 includes：
S410, receives the IP address response message responded to the IP address query messages that terminal is sent from name server, and the IP address response message 7 carries the IP address of server corresponding with the resource of terminal expectation access；
S420, the IP address is obtained according to the IP address response message；
S450, sets up TCP with the server according to the IP address and is connected, in order to which after the resource request message made requests on to the resource of terminal transmission is received, the resource is obtained from the server by the TCP connections.
Alternatively, after agent apparatus obtains IP address, and set up in the agent apparatus and server before TCP is connected, this method 400 also includes：
S430, it is determined that not having the IP address in the IP address list locally preserved；
S440, it is determined that the local TCP set up with the server that is not present is connected.
Alternatively, set up in terminal and agent apparatus before TCP is connected, this method 400 also includes：
