One of the goal of j-t-c, is to be the answer to :

'how to connect my webserver to tomcat ?' 

A great effort has been deployed in having an easy to use 
build stuff. 
Next effort will be documentation and ........... lobbying :)

not in ajp13. But it's successor ajp14, have a strongest login
procedure, and autoconf support (uri handled passed to web-server).
Also planned is to inform the web-server of context state, ie
when a context is put down (for admin purpose), the web-servlet
must learn it and route request to another servlet-engine (if we
are in load-balancing configuration).

what make me think we should add a fault-tolerant/backup-mode worker
in mod_jk. A la load-balancing, having a group of worker (servlet engine),
with one principal, and many as backup. If the principal could no more
handle a request (failure or context down), just have the request 
routed to next worker in list.

What about ?
