I have a situation where I'd like to hide the URL also...but for those who know what they are doing the above frame or javascript solutions would not work.
Situation Explained:
I have a PHP/MySQL message board.
At the bottom of each page is a link for next and previous which, when clicked, cause the next page's URL info to look something like:
http://mywebsite.com/messageboard/view.php?display=10&sort=&entry=10&search=
If someone where to change the value of entry from 10 (entries displayed per page) in the URL to 20000, then 20K posts displayed on a page could really bog down the server.
How do I achieve controlling the display without putting the info in the URL?
