HttpServer should close the connection if response fully sent before request terminated

Here is what we have in the specification

   A server MUST read
   the entire request message body or close the connection after sending
   its response, since otherwise the remaining data on a persistent
   connection would be misinterpreted as the next request.  Likewise, a
   client MUST read the entire response message body if it intends to
   reuse the same connection for a subsequent request.
