Recipe to handle session expiration in ajax calls

Hello,

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   else     page.alert("You're authenticated")   end end

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!
