Apache ProxyPassReverse and https
Solution 1:
This used to work for me
<VirtualHost *:443>
ServerName domaine.com
SSLProxyEngine on
<Location />
ProxyPass https://www.something.com/
ProxyPassReverse https://www.something.com/
</Location>
</VirtualHost>
Solution 2:
The following works for me:
<VirtualHost A.B.C.D:443>
...
ProxyPass / https://192.168.1.101/
ProxyPass / https://192.168.1.101/
</VirtualHost>
(Where A.B.C.D
is your public IP address, obviously)
