Proxy Checker

Hello all. I am wondering if any of you have an example for source code of a proxy checker? If you do or know where I can get one it would be greatly appreciated if you could help me. Thanks very much guys & gals and have a good one. :)

Please anyone at all? I would appreciate it so greatly much. Thanks.

Here's a basic one I started once.

You will want to make it check the header for key items like Client-ip: lines and X-Forwarded-For.... To check the proxy to see weather or not it's anonymous.

Hey. Thanks so much man for that example but 1 thing. It won't check itt. It says checking it on port whatever but then does nothing? WHats wrong? ANyone at all with any ideas/help would be greatly liked and appreciated. Thanks and have a good one.

What that does is open port 80 on your computer, then it splits the proxy server by Address:port, so seperate them with a colon.

Then it sends a POST header with your IP as the host, so in effect the proxy server if valid will send that request back to your computer.

If you simply want a program to verify proxies for you, I suggest Proxy Recon. I based the example off of it's basic design, setting up a web server on the local machine and connecting to it through the proxies in a list.

This is a very thorough program, don't count on getting the source from the author.

Also, it's written in Delphi, not VB.
