page expires using session?

[oh_boy123]

i used session for my web for log-ins.

Now after you logged in, if you click the back button in your browser

sometimes the page expires. How can i solve this problem?

One of my classmate told me to use cookies instead, do i

really have to change it to cookies?

 

thanks.

Unless you want to remember the user after he/she leaves the site and comes back later, then no, you don't have to change to cookies. Otherwise, yes.
