Ok, thank you for this. very appriciated.
Your example is what i have already have for my webapp, which works fine,
but for the outlook client ( over port 237) not. is it that not proxiable?
I’ve now also set the following now in the vhost for outlook.
ProxyPreserveHost On
SSLProxyEngine Off
ProxyRequests Off
SSLProxyVerify none
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
SSLProxyCheckPeerExpire off
any other suggestion? im running out of ideas… :-(
