IPv6 enable an IPv4 only site with reverse proxying
Prerequisites
- mod_proxy is loaded
- mod_http_proxy is loaded
- An AAAA record in DNS with the same name as the website
- An A record in DNS like ipv4.<domain> pointing the same IP as the website.
- Optional: mod_headers if downstream headers need to be modified.

Interesting bit here is what Apache sends to the server downstream. Below is a request header observed via tcpudump. Depending on the far end one may need to modify the headers with mod_headers especially the Host: to make this work.
