konqi> That's pretty much the reverse proxy configuration I've been using for years, with a rewrite rule instead of proxy directives which did not work well here.

RewriteEngine On
# is the virtualhost in the allowed server list ?
RewriteCond %{SERVERNAME} ^(server1|server2|server3|server4)\.domain\.com$
# then redirect to the real server (which the virtualhost name resolves to on the proxy)
RewriteRule ^/(.*)$ https://%{SERVER_NAME}/$1 [P]
# else block it all
RewriteRule ^.*$ - [F]

Plain and simple.

Found this configuration as followed:

  • You have ONE Domain example.com with different subdomains as VHOSTs (one.example.com, two.example.com, ..)
  • You have a Wildcard-Certificate for your domain *.example.com
  • You need mod_proxy
  • with Proxy directives works for different servernames matching *.example.com
  • If there are not other webservers behind the proxy, add without SSL for your domains which are the proxied in the VirtualHost:443 configuration above.

Hot chick! Couldn't believe that this works, but it seems to! Not found any specification to that behaviour, but try yourself.

With kind regards, ~Marcel

P.S: NOT regarding any security doubts here! Please keep in mind that these proxy calls to the "backend" are unsecured and therefore (as like mentioned by Rob) potentially dangerous!

I believe that this cannot be done as it would allow for man in the middle attacks
