I know this is not exactly the place to ask, but it's the best place I know.
I need to outsource a job for my eBay account. To do this, I need to give them my name & password. However, I don't want to give them access to every part of my account. eBay has an authentication process, where if they don't recognize the IP address, they make you verify by phone. If I set up a proxy server on my office computer, I can outsource the work and give them the proxy credentials.
Now, as the administrator of the Proxy server, can I limit the URLs that they are allowed to see?
