How do you find out if a person is using a proxy to visit your website?

Hi everyone, what code do you use to find out if a person is using a proxy to visit your website and why do you use that code?

Thanks

 

All i can say, it is is not worth the hassle. I would recommend you use http://www.ProxStop.com they are the best proxy service in my opinion.

 

For decent proxies it's not possible without a list of IPs of known proxies. Really not worth the hassle.

 

I like that but it's paid service Is there any services for free?

 

Not what i know of, but if i do find one. I will be sure to let you know.

 

okay, PM will be fine, I stopped to monitoring to this thread.

Anyway there are a lot of "lists" of proxies, which ca be blocked

 

Basically the way that I've been checking for proxies is manually add the ip addresses of known proxies and to check for them within whatever script i'm using. I'm looking for a better way though.
