Recipe to handle session expiration in ajax calls



I’m looking for a recipe to handle session logged out or expired in an
ajax calls. For instance, lets say we have a form submission in ajax
that the user needs to be authenticated to perform this action. I’d
like to at least notice the user that he is not logged in anymore or
even better prompt an authentication form.

Any suggestions?

Just return the relevant information from your Ajax call

If you’re using RJS, you could do

render :update do |page|
if authenticated?
page.redirect_to login_path
page.alert(“You’re authenticated”)

Or do you want to periodically make an AJAX call to check if the user
is still logged in? If that is the case you could use the Prototype
PeriodicalExecuter method to call the server and verify that the user
is still logged in. I assume you have some server side sweep that
logs out old sessions. Combined with the periodic AJAX call, the user
would be notified that they were logged out or even better give them
an update that they are about to be logged out!
