            Server Error in '/' Application.

             Object reference not set to an instance of an object. 
 
  
 
[NullReferenceException]: Object reference not set to an instance of an object.
   at xxx.Global.Application_BeginRequest(Object sender, EventArgs e)
   at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)  
  
 so I think, that the problem could be in IIS configuration. 
 My http GET is the following: 
 GET /IsAlive.aspx HTTP/1.1\r\nHost: \r\nConnection: Close\r\n\r\n
