RE: tlug: HTTP headers q

["Frank Bennett" <bennett@example.com>]

Many thanks.  More fiddling has revealed that Apache slaps on a header
even if a valid one is already there: the FastCGI module whinges about
duplicate headers if I put that explict one in in a valid form.

I've also deduced that an empty line does not seem to be needed or
wanted following the headers.

For Tcl too.  I'm using Don Libes' cgi.tcl package, and provides
a cleaner scripting interface for these blocks.  I reverted to explicit
printing statements and conditionals when I lost faith.  :-)  :-(

I've concluded that there's just something wrong with the
order of events in the script; something happens inside that FCGI
loop environment that makes it barf when reinvoked.  I don't have
time to deal with it now, but at least it does appear that I've
bashed the output (when it actually arrives) into a workable form.
