There was a long related discussion a few weeks ago. Here is what I've 
added to the guide (not online yet):


=head1 Verifying Whether A Request Was Received Over An SSL Connection

Just like C<$ENV{MODPERL}> is checked to see whether the code is run
under mod_perl, C<$ENV{HTTPS}> is set by ssl modules and therefore can
be used to check whether a request is running over SSL connection. For
example:

   print "SSL" if $ENV{HTTPS};

If C<PerlSetupEnv Off> setting is in effect, C<$ENV{HTTPS}> won't be
available, and then:

   print "SSL" if $r->subprocess_env('https');

should be used instead.

Note that it's also possible to check the scheme:

   print "SSL" if Apache::URI->parse($r)->scheme =~ m/^https/;

but it's not one hundred percent certain unless you control the server
and you know that you run a secure server on the port 443.
