This took some time. In order to make SSL + Reverse Proxy working another option is needed --> SetEnv proxy-sendcl
Can you explain more about what you did and why you did it? I'm curious.
Forget about "SetEnv proxy-sendcl", I was obviously wrong.
I seems to be a problem with mod_proxy in Apache 2.2.3 (the default Apache used in Centos 5,4) I tried tried Apache 2.2.12 on a Ubuntu workstation and the disappeared.
Any experiences using Apache like this?
