Method for implementing HTTP (hyper text transport protocol) message caching mechanism based on keywords

Abstract

The invention discloses a method for implementing an HTTP message caching mechanism based on keywords. The method comprises the following steps: matching an HTTP request message of a client with a corresponding configuration item; and searching the request message of the client according to the keywords in the configuration item, and determining whether to give an HTTP response to the user from a cache or to acquire a complete HTTP response from a server or to acquire a partial HTTP response from the server and modify the cached message according to the configuration so as to compose a complete HTTP response. By using the method provided by the invention, data traffic between a proxy server and a WEB server is effectively reduced; latency for the client to access a WEB page is effectively shortened; the WEB page requested by the client each time can be ensured to be the updated page; the effects of reducing the data traffic and shortening the latency of the WEB page related to the user status and browser type at the client can also be achieved; and the cache of the WEB page can be optimized according to configuration files.

Description

technical field [0001] The invention belongs to an HTTP network proxy caching method, in particular to a method for scenarios such as reverse proxy, WEB server multi-network acceleration, and more specifically, a method for realizing a keyword-based HTTP message caching mechanism. Background technique [0002] The proxy server is a server between the browser and the Web server. With it, the browser does not directly go to the Web server to retrieve the webpage but sends a request to the proxy server. The Request signal will be sent to the proxy server first. The proxy server retrieves the information required by the browser and sends it to your browser. [0003] HTTP proxy, its function is to proxy network users to obtain network information; now it is also used for WEB website acceleration. Common HTTP proxies are divided into those with no cache mechanism and those with cache mechanism. [0004] HTTP proxy without caching mechanism: The proxy server does not detect the c...

AI Technical Summary

Problems solved by technology

[0004] HTTP proxy without caching mechanism: The proxy server does not detect the content requested by the user, but requests relevant content from the server and returns it to the user; it has the following problems: the HTTP proxy without caching mechanism has large traffic and large network delay; all data needs to be Transmission from the client, proxy server, and WEB server, the network traffic is not reduced, and each step of network transmission has a network delay, which includes:

[0011] 2. Cannot cache pages with the same URL but related to user status

[0012] For example: after a WEB page requires a user to log in, the user name displayed at a fixed position on the page is different, and this kind of page cannot be cached

[0013] 3. The same URL cannot be cached, pages related to browser types
