Thanks David.  I dumped request->env and discovered that *none* of the
three environment variables were set by Apache. I believe I can get Apache
to set these using mod_header. Unfortunately I cannot use mod_header in
this deployment. In this event can I just set the environment variable to
"https" myself? If yes, which is the best place to set it in the
application?

Thank you once again.
