Re: mod_perl2: 304 (not modified) and custom headers

Made a test script:

=============================
#!/usr/bin/perl

use Apache2::RequestUtil;

my $request = Apache2::RequestUtil->request;

$request->headers_out->add('Testheader' => 'Testvalue');
$request->err_headers_out->add('TestheaderErr' => 'TestvalueErr');

$request->status(304);
return 304;
===============================
Returned this:

===============================
HTTP/1.1 304 Not Modified
Date: Wed, 12 Nov 2014 17:45:55 GMT
Server: Apache
Connection: Keep-Alive
Keep-Alive: timeout=30
===============================

And if you set status to 200 - get both headers.
