Re: [MacPerl-WebCGI] dynamic Gifs with MacPerl under MacHTTP 2.2

["Quentin Smith" <macmania@bit-net.com>]

The "correct" way to do it, i.e. the way that is specified in the HTTP RFC,
is \x0D\x0A\x0D\x0A. However, most cgi scripts written for Un*x only print
two linefeeds. Most browsers out there today will handle only two linefeeds.
No browsers today will handle two carriage returns, the Macintosh standard
for text. Now, this all doesn't really matter, because whatever line ending
you use will be translated to \x0D\x0A by the MacPerl CGI glue. You only
need to worry about what you put if the script will need to be cross
platform.
