I've successfully configured Nginx on an Ubuntu 10.04 box, serving up a dynamic PHP website.
We need to be able to reverse proxy this website, which I've also been able to do, as:

www frontend (nginx reverse proxy)
www1 backend (nginx php webserver)

The intention is to be able to add/remove backend servers at will.


The only issue I have so far, is that the frontend, as configured, does not proxy SSL requests.
How can I enable this on my configuration?
Please note, the backend server *does* have functioning SSL config, and was tested directly to verify both :80 and :443 work as intended.

Thanks!
