Create +a `virtual host`_ using the ServerName_ and ServerAlias_ directives to restrict +the domains Apache reacts to. Please keep in mind that while the directives do +support ports the match is only performed against the hostname. This means that +the ``Host`` header could still contain a port pointing to another webserver on +the same machine. The next step is to make sure that your newly created virtual +host is not also the default virtual host. Apache uses the first virtual host +found in the configuration file as default virtual host. As such you have to +ensure that you have another virtual host which will act as catch-all virtual +host. Just add one if you do not have one already, there is nothing special +about it aside from ensuring it is the first virtual host in the configuration +file. Debian/Ubuntu users usually don't have to take any action, since Apache +ships with a default virtual host in ``sites-available`` which is linked into +``sites-enabled`` as ``000-default`` and included from ``apache2.conf``. Just +make sure not to name your site ``000-abc``, since files are included in +alphabetical order. + +.. _virtual host: http://httpd.apache.org/docs/2.2/vhosts/ +.. _ServerName: http://httpd.apache.org/docs/2.2/mod/core.html#servername +.. _ServerAlias: http://httpd.apache.org/docs/2.2/mod/core.html#serveralias + + .. _additional-security-topics: Additional security topics -- cgit v1.3
