Problems solved by technology

[0044] When the proxy server does not change the implementation of the content of the WEB response page, in this case, an external reverse proxy server can only support the website with no absolute URL link on the page, for example, if the returned page contains a link http: / / internal .server.com. / abc.gif, user access will fail
[0045] In the second case, in some implementations, all link URLs that do not meet the requirements are replaced with URLs in a defined format, so that they can be easily accessed outside, but the biggest problem with this method is that it brings great performance. problem, making substitutions when unnecessary is not worth the candle

Embodiment Construction

[0066] Below, refer to the attached Figure 1~4 The method for realizing WEB reverse proxy of the present invention is described in detail.

[0067] Any back-end Web server resources to be accessed from the client must pass through a reverse proxy server. In this way, any valid access request URL sent by the client not only contains the address of the proxy server, but also the address and path of the back-end server. The URL format shown in Table 1 is the formatting request used in the present invention:

Abstract

The invention provides a method for realizing WEB reverse proxy. After the user side inputs a first WEB reverse proxy processing request in the bookmark bar or the interface input box of a browser, the method comprises the following steps: the client transmits HTTP (Hyper Text Transport Protocol) / HTTPS request, the Uniform Resource Locator (URL) of the request includes an address of reverse proxy server SSLVPN (Secure Socket Layer Virtual Private Network), an address of an accessed background server and a resource route of the accessed background server; the reverse proxy server SSLNPN extracts the address and the resource route of the accessed background server and forwards the request normally after intercepting the request. In the invention, a response header processes the HTTP request without any replacement in the HTML (Hyper Text Markup Language) page, a relative URL process and an absolute URL format process based on the redirection can be efficiently finished on the Web server by a formative URL.

Description

Technical field [0001] The present invention relates to WEB proxy technology, in particular to a method for implementing WEB reverse proxy. Background technique [0002] The existing Hyper Text Transfer Protocol (HTTP) request process can be as follows: [0003] The local client connects to the remote HTTP server www.sina.com.cn, and then the client sends the following string to the server: [0004] POST / iframe / 2008 / weather / 110100.html HTTP / 1.1 [0005] Host: www.sina.com.cn [0006] Referer: http: / / news.sina.com.cn / iframe / 2008 / weather / jump_new.html [0007] Cookie: vjuids=20c08e420.11bc93ee742.0.35cc680c38f4e; [0008] vjlast=1226753330; SINAGLOBAL=220.181.35.250.92791219544751236; [0009] SINAPUID=220.181.34.147.306481219848274604; [0010] SSCSum=1; SINA_NEWS_CUSTOMIZE_city=%u5317%u4EAC [0011] user=%61%66%61%66%61%66&passwrod=%66%61%73%66%61%73%66%61%73%66%61 [0012] In the above request, the following items need to be explained: [0013] / iframe / 2008 / weather / 110100.html, the requeste...
