Question : Ajax Make the Back Button work

I am sure this is a common issue and I am looking for a simple solution.

Basically I have an AJAX based ordering process and when users click the back button expecting to go back to a previous step they leave the ordering process. I am trying to figure out how to get past this. I have thought about trying to use # and anchors to try and inject browser history as you jump around but I have been having difficulty making that work, anyone have a solution?

Answer : Ajax Make the Back Button work

However, one way around this is to use what many AJAX folks do -- the iFrames method.  Instead of making asynchronous calls using XML-HTTP requests, you can make your asynchronous calls to a hidden iframe that runs server-side scripts.  If the back button is REALLY important to your application, you can move to this method.
