title: Call page load event on browser's back button press
body: <p>I've written a function on page_load event of aspx page. Problem i'm facing is the function doesn't get call when browser's back button is pressed, or you can say page_load event is not fired. I want to call this function whenever user press browser's back button.
  I've tried </p>
  
  <pre><code>      HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
  </code></pre>
  
  <p>but it didn't worked.
  Please help, thanks</p>
