// colon (":"), followed by a field body, and terminated by CRLF. A
// field name MUST be composed of printable US-ASCII characters (i.e.,
// characters that have values between 33 and 126, inclusive), except
// colon. A field body may be composed of printable US-ASCII characters
// as well as the space (SP, ASCII value 32) and horizontal tab (HTAB,
// ASCII value 9) characters (together known as the white space
// characters, WSP). A field body MUST NOT include CR and LF except
// when used in "folding" and "unfolding", as described in section
