title: HTTP header 'Connection: Close' not sent by IE
body: <p>I have a custom HTTP server that implements the HTTP 1.1 protocol.</p>
  
  <p>I have no problem using persistent connections, however, I never receive 'Connection: Close' from IE ( I haven't tested other browsers. )  Instead, the 'receive' times out because it seems IE closes the connection.</p>
  
  <p>What header from IE should I look for to gracefully close the connection?</p>
