Best thing I ever did, was, on my web hosting I installed phpproxy, took all of 15seconds to install .

It's free, and it works great! I have it under a folder on my hosting, added a .htaccess file and it's password protected too; so for very little effort I have my own (so it always works, no popups/advertising) proxy server. And when the IT man at work looks to see what this URL actually is, he can't find out as its protected!
