Hi
I use one server for my network from which some of my client use private IP (used for local client) and some of my client use public IP (used for bandwidth). There is a web proxy and all public and private ip both is redirected to its port. Now the problem is when any public ip client wants to download from rapidshare.com then it shows my router ip that its already downloading from rapidshare.com. How can i set the rapidshare.com web site not to use proxy for a single public ip or a group of public ip?

Don't redirect traffic destined for rapidshare.com to the proxy.

Please let me know details how can i configure for each site saperately.
