title: how do I delete multiple histories in web app?
body: <p>I'd like to remove multiple browser history at once.  </p>
  
  <p>Suppose your app has a <code>blog-writing</code> task which takes multiple steps/screens/browser history to finish.</p>
  
  <p>When a user completes the blog-writing task, you want to delete the whole writing-related browser histories because when he clicks back button, you don't want him to see his editing screen again.</p>
  
  <p>Conceptually, I'm wondering if there's a way to group multiple browser histories as a task (blog writing task), then kill the histories related to the task. </p>
  
  <p>Then it doesn't matter how many steps you take to perform a task, you can just drop the task when needed.</p>
  
  <p>Can this be done in web environment?  </p>
