I have been banging my head for a few days on this. I have never worked with mod_proxy and it is a little bit over whelming. Here is what I am trying to accomplish. HostA, via HTTPS initiates a request to ServerA which is running Apache and mod_proxy. ServerA should then seamlessly forward the request on to ServerB in plain text html. Unfortunately, ServerB cannot listen on (HTTPS) this is why I need the proxy. Not sure if mod_proxy is what I should be using to accomplish this but from what I read it look possible. Any suggestions would be great. I have also attached a basic diagram of what I am trying to do.
The following in your vhost configuration on servera should get you going: ProxyPass / http://serverb/ ProxyPassReverse / http://serverb/
