Hi, i'm trying to avoid the "304 Not Modified" status when testing my
updated handlers in localhost. From documentation, i read that phase
PerlHeaderParserHandler is the most adequate to launch handlers when
in Directories scopes to manage HTTP response headers.
My apache directive
--------------------------------------------------------
FileETag None
PerlOptions +ParseHeaders
<Directory /home/blogs/camandules.info>
PerlHeaderParserHandler Blogum::BlogumHeaders::nocache
<Files *.js>
PerlHeaderParserHandler Blogum::BlogumHeaders::cache
</Files>
<Files *.gif>
PerlHeaderParserHandler Blogum::BlogumHeaders::cache
</Files>
<Files *.jpg>
PerlHeaderParserHandler Blogum::BlogumHeaders::cache
</Files>
...
</Directory>
--------------------------------------------------------
And my handler
--------------------------------------------------------
package Blogum::BlogumHeaders;
use Apache2::RequestRec();
use Apache2::RequestIO();
use Apache2::RequestUtil();
use Apache2::ServerUtil();
use Apache2::ServerRec();
use Apache2::Process();
use Apache2::Response();
use APR::Table();
# perhaps too modules?
use Apache2::Const -compile => qw(DECLINED);
use strict;
no strict 'refs';
no strict 'subs';
sub nocache {
my ($r) = @_;
warn 'STATUS '.$apache->status();
$r->err_headers_out->add('Pragma' => "no-cache");
$r->err_headers_out->add('Cache-control' => "max-age=0");
$r->err_headers_out->add('Cache-control' => "no-cache");
$r->err_headers_out->add('Cache-control' => "must-revalidate");
$r->err_headers_out->add('Expires' => "-1");
return Apache2::Const::DECLINED;
}
sub cache {
my ($r) = @_;
$r->err_headers_out->add('Pragma' => "public");
$r->err_headers_out->add('Cache-control' => "public");
return Apache2::Const::DECLINED;
}
1;
--------------------------------------------------------
Following HTTP headers negotiation with firefox extension "live http
headers", and the warning of my module, i only get warnings in GET
requests with a status of "200" (in logs there is the 200 number as
expected).
The problem is that when i get the "304" status i get no warning, that
therefore means that the handler is not being executed.
In consequence, how can i avoid this status of 304 with modperl? I
don't know why the server is responding with this status (it
shouldn't), but despite this it seems that it cannot be solves with
modperl.
An example of one HTTP headers negotiation:

I don't know if it is a problem with modperl or with apache, but i
need to solve it before the update to the working server. Do you have
any suggestion of what i can test?
Is it something about mp2 or should i resend this to apache mailing list?
Thanks.
