I’m working on a server side application that runs into trouble when a user hit the back button then submits there information again.

For example:

User uploads file (app does a process)  
Goes to confirmation page  
Hits back button  
Goes through same routine

I need to catch the fact they got back to that page through the browser back button. I’d like to do it client side and not server side. I’m hoping there is a javascript command that will catch it.

Thanks
