[jQuery] Navigate away after ajax call?

[wsw]

My code:

---in the script---
$('a').click(function() {
     $.get('/long_running_page');
     return true;
}

---on the page---
<a href="http://www.otherserver.com";>click here</a.


This appears to work. The long running page finishes (writes a file on
the server) even though I've navigated to otherserver.com by the time
it's done. Is this documented behavior or am I getting lucky?

Thanks!
