AJAX :: Back Button - Broken - On The Internet - Doesn't Work On IE

I'm recently programming a website with ajax and no i have found a solution for the back button problem (broken) on the internet, but it doesn't work on IE. it works on firefox, chrome, safari,...

Every time the user changes the page the url is stored in history with this code:

Code:

It adds after the url a '#' sign with the name of the page...

After that the program will store the url in a non-displayed div

And now i've set up an interval that checks the url adress bar and that div if they are not the same the page will load the url in the adress bar here is the code:

Code:

I've checked the problem with IE. IE will not read the current adress bar. It's always reading the url of the current page but not the url of the adress bar. And i've tried almost every combination with document.location, window.location, href, hash,...at least here's is my url:[url]
