Ahh. I reread your post and now I see what you were originally asking.
Yes, sessions are the best way to handle it then. The variables "live" by
sending a specially augmented header to the client. The header sort of
"sticks" to the client so that their session ID is automatically sent in
their requests for new pages. It's basically a cookie that isn't stored on
the persons hard drive.
There are instances where a person's browser is, for lack of a better word,
"teflon coated" so that the header/cookie just doesn't "stick" to them.
That's when PHP appends the "PHPSESSID=[long string of characters]" to all
of your links.
So the short answer to your question is "Yes, it's the best way to handle
it".
But it must be noted that when someone submits a variable through the URL it
will _not_ change the value of any session variables. You must do that
explicitly in your code.
