title: IIS Request Timeout on long ASP.NET operation
body: <p>I am experiencing a request timeout from IIS when I run a long operation. Behind the scene my ASP.NET application is processing data, but the number of records being processed is large, and thus the operation is taking a long time.</p>
  <p>However, I think IIS times out the session. Is this a problem with IIS or ASP.NET session?</p>
