Tripod

They use a function:
open('filename', '_search') to open the search window

It looks like the href of the 'search' bar is set in a cookie, but it might be window.sidebar property.

It's all in the source, but they've done a good job of making it hard to read.

Scripts are not allowed <see below>

How the heck do they get their search result adverts in the favourites window on IE?
