How to proxy absolutely everything through mod_proxy?

Question

Apache HTTP Server

The server is running apache with mod_proxy. Now I can only proxy individual sites with a similar virtual host:

ServerName mysite.ru
ServerAlias ​​mysite.ru
ProxyRequests Off
RequestHeader unset Accept-Encoding
< Location />
ProxyPass " mysite.ru "
ProxyPassReverse " mysite.ru "
< /Location>

If this is possible, then the next question is how ssl sites will be proxied. Can they use my one and only self-signed certificate?
