There are two ways that you could do it. One is store the session variable into a table, and then on each page at the very top, have a function that checks to see if the session is valid.
Another way to do it is come up w/ ur own encryption scheme and then check if the encrypted session is valid.
You'll have to pass the sessionID and whatever else you are going to check to each page. You can do this by passing the information in the URL

Hi,
Thank you for helping me.

Can you give me an example of session tracking?

I have implemented session tracking in an application of mine which i am detailing below. hope u find it useful...

i am using a combination of the username and the ip address of the user to generate a session variable from page to page. this string is encrypted using md5

this works fine without any problems...

Hi amodi,

i am not clear your explanation.can you show me a couple of lines of code.

You can check out an article that www.phpbuild.com has on session management. It'll probably have some code examples as well.
