Faking out web servers

[Eric "Shubes"]

When I go to http://all-access.cstv.com/cstv/player/player.html?code=osu to 
listen to the OSU game, I get the following obnoxious message:

We're Sorry
But you will need Microsoft Internet Explorer 6 on the following systems in 
order to enjoy All-Access:

Microsoft Windows XP Home/Professional SP2, Windows XP Media Center 2005, 
Windows 2000 SP4; Media Player 9 or 10.

Click here if you're a Mac user.


I seem to remember talk about changing a setting in firefox to make the 
server think that I'm using IE. Any pointers on this?
