Does anyone know where I can find more information on this?
I need a way to add a couple extra variables to all the non-rss links in the site. I figured it could probably be done with a filter, but I haven't been able to find any documentation on it.
The main thing I need to do is tack on a session variable. SO my links to category pages would look like: mysite.com?cat=12&session_id=1234567890
