Problems solved by technology

[0005] Both of the above two methods require the user to modify the page of the WEB server, which cannot be transparent to the application. The two solutions will require the user to have multiple IPs or open multiple ports for the internal security proxy server, especially requiring multiple IPs. In an environment where IP resources are tight, its practicability will be affected to a certain extent

Embodiment Construction

[0018] In the network environment of this specific embodiment, a server with an intranet address is called an intranet server, or an internal server. The WEB server involved in the following is a kind of intranet server.

[0019] The invention sets an alias for each protected WEB server, and establishes the corresponding relationship between each server IP and alias. When the proxy client proposes access to a certain WEB server, the proxy server is responsible for explaining it, that is, the proxy server acts as a virtual DNS server. Such as figure 1 As shown, the steps are as follows:

[0020] (1) The agent client acts as an agent for the connection requests of terminals such as IE, and realizes the mapping between the port and the internal server.

[0021] (2) The proxy server provides the configuration function of WEB server information, and the user sets the IP and alias of the WEB server, which is equivalent to realizing the mapping relationship between IP and domain n...

Abstract

This invention relates to virtual zone name analysis and agent method in computer communication technique, which has servo inner network connected to remote terminal through outer network and terminal connected to the inner net through application agent system, wherein, the said application agent system comprises agent servo and agent customer terminal and the agent servo connects the inner and outer network; the said customer agent terminal is connected to the agent servo through outer net; the terminal visits the inner net servo and its data package is marked by its aim servo by agent customer terminal and is sent to the aim servo after agent servo analysis.

Description

technical field [0001] The present invention relates to computer communication technology, in particular to (safety) application agent technology based on TCP or SSL protocol. Background technique [0002] In the application proxy, the user's proxy server (protected resource) is placed behind the application proxy server (Proxy Server), and the internal address resources need to be kept secret. In order to access the protected WEB server, the application proxy can perform proxy or security proxy without leaking internal address resources through port mapping. But when there is more than one WEB server in the resource to be protected, and there are mutual links between the servers, it is impossible to realize the proxy transparently through port conversion. [0003] Existing (safe) application proxy solution, one is to require the user to modify the link on the relevant page in the WEB server, requiring the link to point to a specific port opened by the WEB server on the pro...
