Try going through an anonimizer, e.g.,
http://www.anonymizer.com
The left side of the screen at that site allows you to plug in the URL and allows you to surf snoop-free (and, possibly allow you to get around you IT nazis).
We discussed this site a few years ago in the context of trying to hide the gifs/jpgs from your cache, and I explained then that the anonymizer likely would not work as that poster needed it, as everything ultimately is captured both at your computer and at your firm's server.
As an aside, if you are using the same computer (laptop) at home and at work, some systems (like the newer Novell) will image/synch your laptop to the firm's system and, therefore, you run the risk of having all your internet files copied onto the system for later persecution by the firm (Jesus, I'm starting to sound like Laird Bell. . .)
