title: Backbone history
body: <p>Is there a way to remove a particular fragment from the backbone history? Here is a use case:</p>
  
  <p>I have a login view, and once the user successfully logs in, there is no need for that view to remain in the history because it is meaningless to go back to the login page after successful login. However, I still need the login view in the history if the user navigates to the login page first, does not login but navigates away from the login page to another page (say password reset page). If the user accidentally clicked on the password reset link and navigated there, clicking on the back button should bring the user back to the login page. </p>
  
  <p>Any chance of doing this with backbone?</p>
