    Hi All,

    I have a really newbie question regarding the Apache Virtualhost directive in the /etc/apache2/sites-enabled files.

    I'm running ISPConfig3. One of my sites http://www.cocoanet.us generates the following VirtualHost directive:

    <VirtualHost *:80>
          DocumentRoot /var/www/cocoanet.us/web
        ServerName cocoanet.us
        ServerAlias *.cocoanet.us
        ServerAlias dantepasquale.cocoanet.us
        ServerAdmin [email protected]
    So, as I understand the documentation from Apache, this directive instructs Apache to listen on all IP addresses on port 80.

    So, my dumb question is: My other sites have the same thing, so how do we actually get to the correct Virtualhost since we don't specify the IP???

    Thanks for answering this dumb question :)

    name based virtual hosting uses the Host header that the client sides through via the request headers.

    The server chooses which site to serve based on the servername and, or the serveralias
