How to change the querystring on the same page without postback

Question

I want to change the querystring on the page where I write notes. When I save the note I want the querystring to have the entry for that note. So after the initial save the user can update based on the querystring. But to update the querystring I need to do full postback. Is there anyway to change the querystring like this?

No, you cannot change the current query string without reloading. You could use the frgament portion of the url though (#). Setting the fragment portion might allow you to add some entries to the browser history without reloading.

For example if your current url is http://example.com/foo you could change it to http://example.com/foo#bar=baz without reloading the current page.
