title: how to clear browser hash history in javascript
body: <p>I use <a href="http://benalman.com/code/projects/jquery-hashchange/examples/document_domain/" rel="nofollow">hashchange</a> plugin to imitate ajax navigation, i would like to create navigation throught folders, for example:</p>
  
  <blockquote>
    <p><strong>#root/ -> #root/folder -> #root/folder/subfolder -> #root/</strong></p>
  </blockquote>
  
  <p>but when i go to last <strong>#root/</strong> in list i would like to clear previous navigation history </p>
  
  <blockquote>
    <p><strong>#root/folder -> #root/folder/subfolder</strong></p>
  </blockquote>
  
  <p>Is any ability to do that?</p>
