title: Nested ASP.NET pages can't access each other's Session variables
body: <p>I have an ASPX page which has an iFrame in it the source of which is an ASPX file as well, on the same domain. What I'm trying to do is - set a Session variable in the parent ASPX file and then access that variable in the file loaded in iFrame. However my inner file (loaded in the iFrame) does not seem to recognize the Session variable from the parent file and I'm simply getting an "Object reference not set to an instance of an object" error on the line where I'm trying to read the value of the Session variable. Could anybody give me a hint on what I'm doing wrong?</p>
  
  <p>Thanks!</p>
