If these referring pages are on your site, I wouldn't count on the
referrer -- set a session variable on each request indicating which
section the user is in, and use that to determine your navigational
include.

If you implement this as a Filter, you don't even have to change any
of the section pages, and you can put the nav mapping in a properties
file to read at application start-up.

If you're not familiar with Filters, see the samples that come with
Tomcat.

HTH!
