-Response automatic values:
- - Auto Server header
- - Auto Date Header
- - code defaults to 404 with body "Not Found\n"
- - if there is a string body add Content-Length and ETag if missing
- - if string body and no Content-Type, use text/plain for valid utf-8, application/octet-stream otherwise
- - Auto add "; charset=utf-8" to Content-Type when body is known to be valid utf-8
- - Auto 304 responses for if-none-match requests
- - Auto strip body with HEAD requests
- - Auto chunked encoding if body with unknown length
- - if Connection header set and not keep-alive, set res.keepAlive to false
- - Add Connection Keep-Alive/Close if not found based on res.keepAlive
