so if i maka a ajax call, and then press \"ba
You should save your ajax "state" in the document location hash (i.e. http://page-url#ajax-state ).
If you modify just the hash component, the browser won't do a page reload, but the browser history will record a change of URL. Therefore, when you press back, you'll be able to re-play the ajax call based on the information stored in the document hash.
