I would like to know what I have to add to the apache.conf file to achieve the following:
For all requests for which no Virtualhost is specified, they have to go to one of the Virtualhosts that I do have specified (but I don't want to use ServerAlias, because there are too many domains which I would have to list). And I also don't want to use the ErrorDocument 404 option, because I already use it.
a request on the direct IP of the webserver will do a redirect to an URL on another server (now I use a php redirect, with an index.php in the www root)
