Hi Rick,
I'm not exactly understanding what you want to do, but it sounds like I a
similar situation I had on one of my sites. This configuration below is what I
used. The new real host is listed first in resin.xml, then the default host
id="" with host-alias * will catch all, and the redirect regex will redirect to
the new site while appending the requested URI.
<host id="foo" root-directory="hosts/foo">
<host-alias-regexp>.*foo.com</host-alias-regexp>
…
</host>
<host id="" root-directory="hosts/default">
<host-alias>*</host-alias>
<web-app id="/" root-directory="webapps/ROOT">
<resin:Redirect regexp="(.*)" target="http://www.foo.com$1"/>
<resin:Redirect regexp="(.*)" target="https://www.foo.com$1";>
<resin:IfSecure value="true"/>
</resin:Redirect>
</web-app>
</host>
Hope this helps,
