Keeping PHP Sessions alive while using JQuery

Keeping PHP Sessions alive while using JQuery

I just started using JQuery because PHP had my pages reloading every time I'd click a button. Now that I use JQuery with PHP, the pages don't reload. I removed the <form> tags and made all my calls to the database go through JQuery. But that's caused yet another problem.

I don't know how to keep my PHP sessions alive now. When the pages were reloading all the time using just PHP, session_start() was called often, keeping the session alive. But with JQuery, this isn't the case. So I'm hoping that someone can offer some insight into how to keep my session alive while using JQuery.
