On Apache 2.2.x I've activated mod_userdir. I used the default setup, so that http://localhost/~name/ will be connect with ~name/public_html/ and a path within public_html, e.g. ~name/public_html/mySite can be reached through http://localhost/~name/mySite. How can I achieve, that the same path can be reached through http://mySite.name.localhost/? I don't want a manual approach like it is suggested in other SF questions (such as http://serverfault.com/q/133921/53624), but rather want an automatic mapping of all available paths to the corresponding URL. I think, several steps will need to be taken: Change mod_userdir configuration, so that the subdomain of localhost will be connected with all available user names on the machine. The second step would maybe include the usage of mod_rewrite, so that the subsubdomain could be matched to the path within ~name/public_html... What would be your prefered way?
