Extend Session Time On Button Click Event Server Side
<p>Is there a way to extend the session of a user the moment they click a button that fires up code behind logic. Example I need to 100 people to a gridview and each time I add a person I want the session to be reset to 30 minutes.</p>

<p>I need to set the timeout on a certain page not the whole site. When a user makes a button click fire the timeout resets. So if the timeout on the page is 30 min, you wait 29 minutes then click the button the timeout is 30 min again.</p>
