Sorry, I debugged it myself.
Don't add extra whitespace lines after you jump out of PHP mode (for
instance, at the end of an include file, don't have any extra lines
after the '?> PHP-jump-out mark'. The extra lines at the bottom of the
functions include file was being interpreted as the end of the headers.
(Man that book on HTTP I was reading at the library came in handy! Perl
Web Client Programming or something)
It isn't truly HTML since it isn't between the <html> and </html> tags,
but it gets sent along as blank lines in the HTML document.
That's my theory , anyway.
