I have this perl filter.
package Test::Filter;
use strict;
use warnings;

use Apache2::Filter ();
use Apache2::RequestRec ();
use Apache2::Const -compile => qw(OK DECLINED);

sub handler {
my $f = shift;
my $r = $f->r;
my $content_type = $r->content_type();
my $handler = $r->handler;
my $encoding = $r->content_encoding();
unless (defined ($content_type)) {$content_type =0}
unless (defined ($handler)) {$handler =0}
unless (defined ($encoding)) {$encoding =0}

open (LOGG, ">>", "/path/to/log");
print LOGG "Encoding: $encoding \nContent: $content_type \nHandler: $h
+andler \n";
close LOGG;


while ($f->read(my $buffer, 1024)) {

$buffer =~ s!(<body>)!$1<h1>TEST</h1>!i;
#if ($encoding =~ /gzip/i) {#do something}
$f->print($buffer);
}

return Apache2::Const::OK;
}
1;

http://www.gidnetwork.com/tools/gzip-test.php shows correctly content encoding for a smforum (gzip).
However my filter always return not defined value for $encoding value :(

I want to use this filter to automatically add html code for compressed content as well. Filter working without problem for uncompressed content.
Any help would be greatly appreciated. Thank you!
