The ServerName doesn't matter, since it's not used in the ProxyPass. Just make that server.de or whatever. Then create a ServerAlias *.server.de. Keep in mind that this setup allows something like a request to localhost-80.server.de which then gets proxied to localhost:80 and might serve things that were supposed to only be accessed locally. I'm not sure why you want to proxy. Is this something that could be solved using mod_vhost_alias ?
