Hyperlink tracking

[WashCup]

We just had this server set up at my work that has a program called Websense installed on it. Basically, it blocks users from visiting certain sites (i.e. MS hotmail) and also prevents certain web-based downloads. Now they want to configure it so that they can view every hyperlink visited by username and IP address. Anyone know of a way to perhaps "disguise" my username and/or IP address or some other preventitive method to avoid being tracked by this program??
