// The normal procedure for parsing an HTTP message is to read the
// start - line into a structure, read each header field into a hash table
// by field name until the empty line, and then use the parsed data to
// determine if a message body is expected.If a message body has been
// indicated, then it is read as a stream until an amount of octets
// equal to the message body length is read or the connection is closed.
// https://tools.ietf.org/html/rfc7230#section-3
// All HTTP/ 1.1 messages consist of a start - line followed by a sequence
// of octets in a format similar to the Internet Message Format
// [RFC5322]: zero or more header fields(collectively referred to as
// the "headers" or the "header section"), an empty line indicating the
// end of the header section, and an optional message body.
// HTTP - message = start - line
// * (header - field CRLF )
// CRLF
// [message - body]
