[jQuery] Can I change the URL address of my


I searched google and jQuery site, but found nothing helpful.
My requirements are:
1. When I do something in the page, the URL address of browser can be
changed accordingly.
2. So, the user can copy & paste the URL for later usage.
3. No HTTP request send out because I don't want to reload the entire
page.
Any help?
Many thanks.
