I go to different clients and they all have their networks with different proxy settings. So I'm always having to change the proxy settings and saving the info in a notebook, and it becomes a pain after a while.

So, any good way to save all those proxies and have them recognize the network I'm on and load up?

Currently I maintain two: one in IE for clients, and none in Firefox for when I'm at home.

And I think the last network I was on asked me to save the proxy and I think it went to system settings. But I don't know much about networking.
