I was beginning to think no one was going to reply.
I store all of my data in cookies so that I do not have to retrieve the
same data over and over as you stated.
For example, on one of my sites users can only hit the pages that they have
paid for. So, when they login the first thing I do is set a cookie that
lists all of the pages that they can hit.
I also store what layout the user has selected as well as any color
variables I need. But once I store them I do not hit the database again
unless they make a change to their preferences.
So what you are saying is that you are passing these session variables
through the url on every page request? And that you find this much more
effective then storing this data in cookies?
