Use with mod_proxy?

[bdushok]

I'm using mod_proxy in front of an internal https server. I'm using a location as follows:

AuthType Digest AuthName "Please login" AuthDigestUserFile /usr/local/apache/accounts.pwd Require valid-user ProxyPass https://internal server/ ProxyPassReverse https://internal server/ Order allow,deny Allow from all

This works great and authenticates perfectly before proxying the traffic. I would love to use Google Authenticator with this, but this module seems to require it's config to be in a directory, not location. Is there any way to make this work with Location so I can utility mod_proxy?

Thanks,
Bob
