[users@httpd] Content-Length HTTP/1.0 BUG
I'm trying to use Apache 2.0.40 but I can't force my cgi to hot flush the
output to the browser using HTTP/1.0.
tick.cgi:
--- snip ---
#!/usr/bin/perl
print "Content-length: text/html\n\n";
$| = 1; # TRY REALLY REALLY REALLY HARD TO FLUSH
print "Timer running...<br>\n";
for (1..10) {
print "Test $_<br>\n";
sleep 1;
}
--- snap ---
$ telnet localhost 80
GET /cgi-bin/tick.cgi HTTP/1.0
[.... chokes for 10 seconds before saying ANYTHING!]
If I downgrade to Apache 1.3.27, everything works perfectly.
Or if I switch HTTP/1.0 to HTTP/1.1 then everything work perfectly.
Is there a -DDONT_CHOKE option or some configuration
directive that I can add to force my cgis to really
really really really flush the output to the browser
on the fly using HTTP/1.0 under Apache 2.x? I could
care less if there's no "Content-Length" header or if
it's inaccurate. It seems like someone went to a lot
of work to add a "Content-Length" header when I don't
need it nor want it. How can I skip it? I couldn't
find anything in the documentation.

PLease try a more recent version of apache. It works very fine here:
(nph-tick.pl)
#!perl -w
print "HTTP/1.0 200 OK\n";
print "Content-type: text/html\n\n";
$| = 1; # TRY REALLY REALLY REALLY HARD TO FLUSH
print "Timer running...<br>\n";
for (1..10) {
print "Test $_<br>\n";
sleep 1;
}
__END__

The nph-tick did make it non-parsed script,
yet it still hung exactly like before.
That totally did not work.

simply rename your script to nph-tick.cgi. nph-scripts skip all filters
beyond connection filters.

My bad. I totally meant "Content-Type" instead of "Content-length"

It isn't perl. It's within Apache itself.

I thought Content-length was supposed to be a number not a MIME type?
Does perl have a flush() function?

Try the latest version (2.0.44). At some point, the content-length filter
was made less agressive about queing up the contents.
