John,
it took me almost 2 weeks to go from 0 to 60 using Tomcat, JBoss, and
I believe the following approach would be possible:
1) Build a URIResolver and have it cache all the include lookup URIs in a
hash table along with the cache currency info (last modified, or whatever).
2) Upon recall of the original including resource, run the hash table
getting each lookup and

Umm, you can always arrange to pass the request parameters back for a 2nd
