Method and device for sending requests

A method for sending requests, comprising:

• determining, by a device comprising a processor, the requests and Transmission Control Protocol (TCP) connections between a client and a proxy server;
• and
• sending, by the device, the requests to the proxy server via idle TCP connections between the client and the proxy server so as to forward the requests to a Web server by the proxy server, if the requests are serial requests and the idle TCP connections exist between the client and the proxy server, or if the requests are serial requests and the number of idle TCP connections between the client and the proxy server is larger than or equal to the number of TCP connections which are needed during sending the requests;
• or
• establishing, by the device, TCP connections between the client and the proxy server according to the number of idle TCP connections between the client and the proxy server, and the number of TCP connections which are needed during sending the requests, if the requests are parallel requests and the number of idle TCP connections between the client and the proxy server is smaller than the number of TCP connections which are needed during sending the requests;
• and sending, by the device, the requests to the proxy server via the idle TCP connections between the client and the proxy server and the established TCP connections so as to forward the requests to the Web server by the proxy server,
• wherein before sending the requests to the proxy server via the idle TCP connections between the client and the proxy server, the method further comprises:
• obtaining the identification of the idle TCP connection in a corresponding relationship between the identification of the TCP connections and a TCP connection status locally stored in the client;
• and
• obtaining the TCP connection corresponding to the obtained identification of the TCP connection, wherein the obtained TCP connection is an idle TCP connection between the client and the proxy server.

• and sending, by the device, the requests to the proxy server via the idle TCP connections between the client and the proxy server and the established TCP connections so as to forward the requests to the Web server by the proxy server,
• wherein after establishing the TCP connections between the client and the proxy server, the method further comprises:
• setting the connection status of the established TCP connection as busy status;
• and
• storing the identification and connection status of the established TCP in the corresponding relationship between the identification of the TCP connection and the TCP connection status locally stored in the client.

A device for sending requests, comprising:

• a determining module configured to determine the requests and TCP connections between a client and a proxy server;
• a first sending module configured to send the requests to the proxy server via idle TCP connections between the client and the proxy server so as to forward the requests to a Web server by the proxy server if the requests are serial requests and there are idle TCP connections between the client and the proxy server, or if the requests are serial requests and the number of idle TCP connections between the client and the proxy server is larger than or equal to the number of TCP connections which are needed during sending the requests;
• and
• a second sending module configured to establish the TCP connections between the client and the proxy server according to the number of idle TCP connections between the client and the proxy server and the number of TCP connections which are needed during sending the requests;
• and to send the requests to the proxy server via the idle TCP connections between the client and the proxy server and the established TCP connections so as to forward the requests to the Web server by the proxy server, if the requests are parallel requests and the number of idle TCP connections between the client and the proxy server is smaller than the number of TCP connections which are needed during sending the requests.
