Apache::Dynagzip not seeing my headers from Apache::Registry script

[prev] [thread] [next] [Date index for 2004/12/24]

Hi,


I've been trying for most of the evening to get Apache::Dynagzip
working with Apache::Registry. I've gotten to the point whereby it
works fine (compresses the content or not depending on the browser),
but it sets the default Content-Type to text/html and disregards the
headers I send from my script.


The code below produces the following when called from a non-gzip browser:


#!/usr/local/bin/perl

use strict;

my $r = Apache->request;

my $var;

open(FILE, "text.txt");

while (<FILE>)
{
        $var .= $_;
}

close(FILE);

$r->content_type("text/plain");
$r->send_http_header;

print $var;

Note that Apache::Dynagzip is setting the header to the default
text/html even though I have explicitly set it to text/plain. The
following debug is from the error log:


[Fri Dec 24 23:29:10 2004] [info] [client 192.168.1.6]
Apache::Dynagzip default_content_handler is serving the main request
for GET /cgi-bin/blah.cgi HTTP/1.1 targeting /www/cgi-bin/blah.cgi via

Chain. The client  does not accept GZIP.

/usr/lib/perl5/site_perl/5.8.3/Apache/Dynagzip.pm(917): [client
192.168.1.6] Apache::Dynagzip default_content_handler creates default

Apache::Dynagzip default_content_handler is done OK for
/www/cgi-bin/blah.cgi 40172 bytes sent


What's even stranger is when I use the same check that Dynagzip uses
to see if the Content-Type is set, it fails. Appending this to my
script:

if ($r->header_out("Content-type"))
{
        warn "Headers sent OK";
}
else
{
        warn "Headers NOT sent OK";
}


Results in the following in the error log:


Headers NOT sent OK at /www/cgi-bin/blah.cgi line 29.


My Apache configuration is as follows:


<Directory "/www/cgi-bin">
        SetHandler perl-script
        PerlHandler Apache::RegistryFilter Apache::Dynagzip
        PerlSetVar Filter On
        PerlSendHeader Off
        PerlSetupEnv On
        AllowOverride AuthConfig
        Options +ExecCGI
</Directory>


Any advice on this would be much appreciated, as I have been banging
my head against it all evening!
