Elite Proxy Server_Detect

Recommended Posts

Anonymouse web proxy can be detected using "HTTP_X_FORWARDED_FOR"  with other similar  tags including some array using ports definitions though it is not 100% efficient. But I have heard that "Elite Proxy Server" cannot be detected at all. Is it true ? or is there any loophole in it, so that some code using PHP can be used to detect Elite Proxy server. Does anyone can give tips about it? Anyone tried using some PHP code to detect it? Or is there any special software that can be uploaded in our server. Please help. Thanks

A lot of these types of identification strings come from the client, therefore they are dependent upon good behavior. The same goes for proxy servers. In the case of a proxy server, it is making the actually connection to the server, and not the client directly. If it's well behaved it will provide the HTTP_X_FORWARDED_FOR. If it chooses not to, the server has no way of knowing that the client was a proxy server.

 

As far as "Elite Proxy Server" is concerned, I have no idea what that is, but it seems like some scammy marketing phrase that has no specific technical meaning. From what I gather you are associating the term to mean a proxy server that doesn't pass on the client IP in the HTTP_X_FORWARDED_FOR variable.

 

If this was important to determine, you could maintain a database of proxy servers and use that information to do whatever it is that you are concerned with, but that will never a perfect answer, because that data can be whatever the "client" wants it to be. This is similar to HTTP_USER_AGENT or the use of a robots.txt. Many sites implement controls or behavior based on HTTP_USER_AGENT but clients routinely spoof that string for their own purposes (bots masquerading as a specific browser for example).
