Host-default
From CauchoWiki
Contains default <host> configuration for all virtual hosts in a <server> (or in a <host-deploy>.)
host-default can be useful for configuring all virtual hosts with a common directory structure or access logging. For example, to configure all virtual hosts to use a webapps directory and have a separate root web-app in docs, you could use:
[edit] resin.conf
...
<server>
<host-default>
<web-app-deploy path="webapps"/>
<web-app id="/" document-directory="docs"/>
<access-log path="log/access.log" .../>
</host-default>
...
</server>
..
