Editor to share with you an example analysis of the principle of Gaoni agent ip, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Principle of Gao Ning Agent ip:

1. An agent with high anonymity will not change the client's request.

Because when the client's IP is hidden, the server will feel that a real client browser is accessing it, and the server will not think that we are using a proxy.

2. For highly anonymous agents, both the other server and the real IP are hidden. The highly anonymous proxy accesses the HTTP header information of the other server as follows: proxy server IP=REMOTE_ADDR=.

General anonymous agents can hide the real IP of the client, but adjust the request information, and the server may think that we are using the proxy (this is only possible, usually no problem), but in fact, this kind of proxy has higher security than highly anonymous agents, and some agents even separate the information sent by the client. Makes it impossible for the server to find the version of the operating system and browser.

So how to detect Gao Ning agent IP? For highly anonymous proxies, both the server and the real IP are hidden. The highly anonymous proxy accesses the HTTP header information of the other server as follows:

Proxy server IP=REMOTE_ADDR=.

HTTP_VIA is not displayed.

HTTP_X_FORWARDED_FOR is not displayed.

From this HTTP header information, you can fully determine whether it is a highly anonymous agent ip.

The above is all the contents of this article "sample Analysis of the principle of Gaoni Agent ip". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
