Javascript. Check time against session expiration every X seconds. Use modal to confirm user wants to extend session when they need to. Send request to server if they do, which should automagically keep the session ball rolling.

OOoooh. That is a really good idea. Was just looking at how to do this myself and was stuck. But that is a really cool plan. Not sure how to do that in js but it is a good sounding approach. Thanks.

jQuery AJAX POST to a controller, return JSON encoded reply, have the JS pop a modal at the right time for the user to maintain the session (with a count down so the user has a sense of "I should take care of this").
I do jQuery AJAX calls all of the time, it isn't that difficult, pretty sure you'll get it Smile

I've never actually done this. I was just thinking as I was typing. I think you could do the looping with setInterval, like this:

Get the epoch time in javascript:

Put the epoch time of session expiration in a hidden input so javascript can see it easily....

If expiration is less than X seconds, add a class or attribute to hidden input, so that the loop quits checking the time, then pop up the modal ....

This wouldn't work because the ajax post to the controller would automatically extend the session, unless you're not autoloading the session, which I think is rare for people who use sessions.
