This will give you transparent SSL termination for Apache VirtualHosts located behind an Amazon EC2 Elastic Load Balancer.
In this setup, clients connect to the ELB via SSL and the ELB forwards the connection as plain HTTP to your virtual host.

Especially the REMOTE_ADDR, HTTPS, SCRIPT_URI and HTTP_PORT server variables will be what you would expect for a direct connection.
