Because you want different sets of webapps served on your different
connectors, I *think* you'll need two different Services in your server.xml:
<Server>
<Service> for port 80
<Connector> for port 80
<Engine> for port 80
<Host> for port 80, specifying base directory for your port 80 webapps
</Engine> for port 80
</Service> for port 80
<Service> for port 666
<Connector> for port 666
<Engine> for port 666
<Host> for port 666, specifying base directory for your port 666
webapps
</Engine> for port 666
</Service> for port 666
</Server>
The fastest way to make such a configuration will be to edit your existing
server.xml, copy+paste the <Service>...</Service> section (which is most of
the file) and hack at the copy as necessary.
Note that you'll end up with two independent copies of the servlet in your
two webapp directories, and they won't share things like Sessions between
them. I can't think of a way of doing that using just Tomcat's features.
You might, however, be able to get what you want using a combination of
http://tuckey.org/urlrewrite/ and two Connectors defined on the same
Service.
Good luck!
