mod_auth_openid fails when behind a reverse_proxy

[bmuller@…]

When runninng behind a reverse proxy and using a private IP that points to a private DNS, the full_uri function of /libapache2-mod-auth-openid-0.1/mod_auth_openid.cpp will not use the FORWARDED variables to figure out the public DNS name to which the request was originally sent. As a consequence it cannot work at all, because the originating URL cannot be set manually.

There are two ways out : a configuration variable that sets the originating domain or handling the FORWARDED environment variables.
