title: using Request.UrlReferrer in vb.net code
body: <p>i saw this article on msdn forum about Request.UrlReferrer but didnt really understand it well. I need to use this property in one of my pages to see where the user is coming from. My case is if the user comes from certain page, i need to have an if condition and should open up a popup as well as redirect page to next page. if the Request.UrlReferrer is null then i dont need the popup, just goto next page. can somebody put a sample code snippet here?
  this is what i have so far -</p>
  
  <pre><code>Public ReadOnly Property URLReferrer() As uri
      Get
  
      End Get
  End Property
  </code></pre>
  
  <p>i am not sure what to put with the Get and End Get. </p>
