| Thanks,

RFC2616 [1] is your friend.

Section 5 describes the format of a request as:

~ Request = Request-Line ; Section 5.1
~ *(( general-header ; Section 4.5
~ | request-header ; Section 5.3
~ | entity-header ) CRLF) ; Section 7.1
~ CRLF
~ [ message-body ] ; Section 4.3

Further up, in section 2.2 it describes the meaning of CRLF:

CRLF = CR LF
where CR = <US-ASCII CR, carriage return (13)>
and LF = <US-ASCII LF, linefeed (10)>

Definitely an interesting read (if you're cool like that) ; I keep mine next
to the john ;p
