Using the back button to reverse the effects of AJAX in my web application

Question

I am using ajax to load into an element on my page, but I want this action to be reversed with the back button ... I'd rather the URL change to a real URL like mysite.com/page1 rather than mysite.com/page#page1

I read somewhere about using a hidden iframe to achieve this ? Can anyone help me out?

Answer 2

I use a technique similar to Really Simple History.

I have a hidden Iframe to which I route all JS calls that manipulate the DOM, which in-turn routes them back to the parent page.
