Handlers Communication

Apache handlers can communicate between themselves by writing and reading notes. It doesn't matter in what language the handlers were implemented as long as they can access the notes table.

For example inside a request handler we can say:

  my $r = shift;
  my $c = $r->connection;
  $c->notes->set(mod_perl => 'rules');

and then later in a mod_perl filter handler this note can be retrieved with:

  my $f = shift;
  my $c = $f->c;
  my $is = $c->notes->get("mod_perl");
  $f->print("mod_perl $is");
