I wasn't particularly conscious that night. I actually meant this:

printf("Content-Type: text/html\r\l\r\l");

From RFC 2068, the HTTP/1.1 spec:

"HTTP/1.1 defines the sequence CR LF as the end-of-line marker for all
protocol elements except the entity-body (see appendix 19.3 for
tolerant applications). The end-of-line marker within an entity-body
is defined by its associated media type, as described in section 3.7.

CRLF           = CR LF"

where:

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

Since "\n" = CRLF for text mode I/O with DJGPP, this a moot point. On Unix
\n = \l. Fortunately it also says in the HTTP/1.1 spec that applications
can ignore the leading CR of the CRLF or accept just an LF if they want,
presumably to avoid this \n = \r\l vs. \n = \l mess. So double \n is OK,
and I really shouldn't post when I'm tired. =o

Bye,
