Looking JS script tries to convert my site to site full ajax

I am looking for a JavaScript that turns a traditional site full ajax website.
This kind of script changes the links (usually adds a # in front of each link) and loads pages via JavaScript.
I’ve already found two (http://fullajax.ru/ and http://www.bydust.com/examples/com.bydust.ajax/), but it does not work well and does not load urls rewritten.

Thank you.
