I have a page, that adds a filter to a mason generated page. The filter takes the output and converts it to a csv. The csv is sent fine, but none of the headers are being sent. I've been setting the headers by doing the following: 
$r->err_headers_out->{'Content-Disposition'} ="attachment; filename=\"
+$csv_file\"";
  $r->headers_out->{'Content-Disposition'} ="attachment; filename=\"$c
+sv_file\"";
  $r->headers_out->{'ABZZ-Disposition'} ="attachment; filename=\"$csv_
+file\"";
  $r->content_type('text/csv');
  $r->set_content_length([stat $csv_fh]->[7]);
  $r->rflush();

And then send the file via this:
 $r->sendfile($pdf_file);

My question is what am I doing that headers aren't being sent?
