Thanks for the suggestion - its taken a while but I've manage to free
up a machine to roll forwards and test on; unfortunately I've got no
experience with Apache and filters. I've come up with this:
package Zymonic::Decryptor::Filter;
use strict;
use base qw(Apache2::Filter);
use Encode qw(decode);
use constant BUFF_LEN => 1024;
use Apache2::Const -compile => 'OK';
sub utf8_filter : FilterRequestHandler {
my $f = shift;
my $content = '';
while($f->read(my $buffer, BUFF_LEN)) {
$content .= decode_utf8($buffer);
}
$f->print($content);
return Apache2::Const::OK;
}
but when I add it with:
PerlOutputFilterHandler Zymonic::Decryptor::Filter::utf8_filter
I get:
:Apache2 IO flush: (500) Unknown error 500 at -e line 0
in the Apache error log whenever I hit the server with a request.
I'm guessing I've done something very wrong with the filter, but I can
find very few examples of how to use Apache2::Filter.
Thanks,
Alex
