Because server needs the long-time state information safeguarding long connection, the long connection of HTTP can increase the memory usage of server.Consider the long above advantage connected of HTTP, especially reduce the network that connects consuming time in advantage (in slow wireless network as in 2G, 3G, 4G, WiFi, it is always consuming time that the long connection of http can significantly reduce network), HTTP long connection has become one of main method of wireless application performance optimization at present, current each main flow Web server and browser are all supported that HTTP is long and are connected, and HTTP long connection is applied in more and more widely in wireless B/S application.Wherein, long connection multiplexing rate is defined by following formula:
The HTTP request number that the HTTP request number/user of long connection multiplexing rate=multiplexing is total
Long connection multiplexing rate depends on the HTTP request number be re-used as can be seen from the above equation, and the long connection that the HTTP request number be re-used depends primarily on server or intermediate proxy server is held time, long connection is held time longer, and the probability of HTTP request this connection multiplexing is higher.The maintenance mode of current long connection, mainly through timeout mechanism, namely controls the long time connecting maintenance by the long series of parameters such as timeout value that connect of Web server, browser, intermediate proxy server.Because the overtime relative parameters setting difference of all kinds of server and browser is comparatively large, the time-out of Web server and intermediate proxy server arrange inharmonious long connection all can be caused to be re-used or reusability lower, therefore, although long this characteristic that connects of HTTP is extensively supported by major browsers and Web server, the connection multiplexing rate in network is unsatisfactory.
In prior art, support that the method for the long connection of HTTP and lifting connection multiplexing rate mainly contains following several:
1) in current network, still HTTP1.1 agreement do not supported by some older Web server and browser, thus the long connection performance of HTTP is not supported yet under default situations, for this kind of Web server and browser, can force to make it support the long connection of HTTP by interpolation Connection:keep-alive field manual in HTTP head, namely revise HTTP header information and make it support the connection of HTTP length.
2) major part is supported to Web server and the browser of HTTP1.1 agreement, browser head when sending HTTP request is default with Connection:keep-alive field, shows to give support to the long connection of HTTP.In this case, long connection multiplexing rate depends primarily on the long maintenance situation connected.The current long maintenance connected controls mainly through the timeout mechanism of server, the parameters such as the long multiplexing main maximum number of connections by time-out time, the upper service of each long connection connected determine, therefore, connection multiplexing rate is promoted by the long join dependency parameter configuration of Optimized Service device, browser and intermediate proxy server.But, the long join dependency optimum configurations difference of different Web server and browser is larger, the time-out time of such as IE8 browser is 60 seconds, the time-out time of Chrome browser is 45 seconds, the time-out time of Apache Server defaults to 5s, due to all kinds of server, browser, the long join dependency parameter difference of intermediate proxy server is larger, the long join dependency parameter configuration of Optimized Service device and browser is individual engineering end to end, and often with user access pattern and server load condition dynamical correlation, be difficult to accomplish accurate configuration, therefore, the connection multiplexing rate of current wireless application is still undesirable.
3) the TCP connection closed request that mandatory modification client sends, forces to make it keep connecting.The method of mandatory modification TCP connection closed needs the amendment authority of client browser, but most of wireless application there is no this authority, and therefore, the feasibility of which is lower.
