title: Httpcontext is null?
body: <p>Is it right to say that when Httpcontext object is null  - so the iis is down ?</p>
  
  <p>i know that when the first request to iis ( asp.net) the application manager creates </p>
  
  <p>enviroment : Application Domain.</p>
  
  <p>inside it theres Application Runtime.</p>
  
  <p>And inside it there's blocks of (if theres more then 1 application on the server) </p>
  
  <p>HttpApplication with each has  httpContext which handler Response and Request.</p>
