if you define several domains in ejabberd.cfg (see section <A HREF="#hostnames">3.1.1</A>),
you probably want that each virtual host uses a different configuration of database, authentication and storage,
so that usernames do not conflict and mix between different virtual hosts.
For that purpose, the options described in the next sections
must be set inside a <TT>host_cofig</TT> for each vhost (see section <A HREF="#virtualhost">3.1.2</A>).
For example:

Important note about virtual hosting:
if you define several domains in ejabberd.cfg (see section \ref{hostnames}),
you probably want that each virtual host uses a different configuration of database, authentication and storage,
