title: How do I achieve navigation without affecting browser history?
body: <p>If you go here: <a href="http://twitter.com/account/resend_password" rel="nofollow">http://twitter.com/account/resend_password</a></p>
  
  <p>Then click on "Send Instructions" without filling in the form, it appears to be doing a full, non-ajax request.</p>
  
  <p>However, if I look at my browser history, the previous page (resend_password) isn't in the history. It's as if it made an ajax request.</p>
  
  <p>What is twitter doing? Is this really just an ajax request, or is it doing something tricky?</p>
