      Yes. That's a good approach to caching the session for the length of a
      request.

        With MasonX::Request::WithApacheSession, this should happen automatically,
        since the session is stored in the request object, and the request object
        only lives for a single request.

          It would still be possible to screw this up if someone copied it into a
          global or made a closure, intentionally or not. That's what I would
          look for.

            I want to find out what the scheme (http, https) was for the current request.

                    Ai, my bad, sorry about that. I *should* have tested that.

                    I don't think you can get the request's scheme, because the server doesn't
                    know it. it's only used by the client. The server gets only the request URI.

                    You can get the scheme only if you know the whole thing, e.g.:

                    APR::URI->parse($r->pool, "http://localhost:9000/foo/bar")->scheme;

                    You can check what's the currently used protocol with $r->protocol, but it'll
                    be the same with http:// and https://. CGI.pm does:

                    sub protocol {
                    local($^W)=0;
                    my $self = shift;
                    return 'https' if uc($self->https()) eq 'ON';
                    return 'https' if $self->server_port == 443;
                    my $prot = $self->server_protocol;
                    my($protocol,$version) = split('/',$prot);
                    return "\L$protocol\E";
                    }

                    so you can either use CGI.pm or copy it away.

                      there was a way to do this in mod_perl 1.0. I'll take a look tomorrow and
                      see if the same functionality was copied over.

                        Thanks,

                        I'll use the

                        return 'https' if uc($self->https()) eq 'ON';

                        approach.
