Well, With javascript it is going to require you to use cookies. You send the browser a cookie, with the value as the number of visits. Next time they return, read the cookie, increment it, and over-write the cookie with the new value. In order to do something like this SERVER SIDE, you'll need a server side language, such as perl, php, or some other server side programming language.

Thanks Comatose!!!
But, what I want to know is give me some code to implement this in SERVER side using PHP, PERL,etc and how to apply it.
