How can I make it so that when a user hits their BACK button, whatever they typed into the form on the previous page is still there? I know this is not a browser issue because on other sites I visit I can hit the back button and still see what was submitted to the form no problem, just for some reason on the site I'm working on now it's gone every time I go back.
Is there some doctype or tag or something that can be placed on a page to control this?
