title: Remove content of asp.net session while navigating onto another page
body: <p>I have a session variable that I am using on a page. I know that sessions should be used for the purpose
      of storing data between different pages of a website, but I have a big dataset to store and I am using a session instead of a view state.</p>
  
  <p>I would like to empty the session when I navigate to another page. </p>
  
  <p>Is there a way I can do it ?</p>
  
  <p>I tried setting the session variable to null on the PageUnload event, but thats not what I want. </p>
  
  <p>I would like to set the session variable to null while the page is navigated to another page. </p>
  
  <p>Please let me know. </p>
