We happen to have more than just a username and user id though. We use it to pass other dynamic information pages as well. But the solution is far from silly, and it's a lot more common than you may think. In some situations, yes. We happen to have more than just a username and user id though.

The tip about using Javascript for the variable part of a page is just great. As all really good ideas, seems obvious in retrospect. Thanks a lot for sharing. Very nice article.
