Hi, I tested and I got "ssl error code 47" error. It seems to me that Apache wants to terminate any port 443 traffic. The Citrix presentation server does not allow termination of the traffic at port 443. Otherwise Citrix will have an error. Is there a way to let Apache proxy server passing port 443 traffic without doing anything like a firewall does? Thanks.

You need SSLProxyEngine on, and then ProxyPass / https://backend/ (the ProxyPassReverse line is probably unnecessary because it's not https-traffic, but it won't kill you to add it anyway).
