+To add a virtual host, add a `CNAME` pointer to the DNS for your domain

+The first line will rewrite the request to display the content of the `example`

+Rewriting Hosts to path
+-----------------------
+
+Like in the :ref:`_rewrite <api/ddoc/rewrite>` handler you could match some
+variable and use them to create the target path. Some examples::
+
+  [vhosts]
+  *.couchdb.local = /*
+  :dbname. = /:dbname
+  :ddocname.:dbname.example.com = /:dbname/_design/:ddocname/_rewrite
+
+
+First rule pass wildcard as `dbname`. The second one does the same, but uses a
+variable name. And the third one allows you to use any app with `ddocname` in
+any database with `dbname`.
+
+You could also change the default function to handle request by changing
+the setting :ref:`redirect_vhost_handler <config/httpd/redirect_vhost_handler>`
+in :ref:`httpd <config/httpd>` config section.
