title: Session_Start & Session_End in Global.asax.cs
body: <p>To which events of which class do these 2 event handlers belong?</p>
  
  <p>For instance <b>Application_BeginRequest</b> in <b>Global.asax</b> is registered to BeginRequest of HttpApplication class by naming convention.</p>
  
  <p>I couldn't find anything in these 3 classes regarding those 2 session events:
  <b>HttpApplication</b>, <b>HttpContext</b>, <b>HttpSessionState</b></p>
