I am using ajax on my site.
If the user enters a query and selects a category, I refresh the page with the result using ajax. I am also updating the URL with a hash value that shows the request and category, separated by a character &.
I want that when I click the "Back back" button, I want to display the previous result without rebooting. I get the url to have the previous values, but the result is not updated.
