Well, jk_uri_worker_map is common for all, so if it's implemented in one
it'll be implemented in all :-)

The only problem is that regardless of the protocol or configuration
mechanism, we need to:
- collect all relevant information from web.xml, server.xml and pass it to
mod_jk/web server.
- as long as mod_jk ( using either autoconf or generated or generated native config ) can't handle all
settings in web.xml, we should default to sending all requests for a
context to tomcat. A small improvement will happen in ajp14, where we'll
be able to tell mod_jk to send chunks ( so static files will be served by
apache, but with an eventual round trip to tomcat )

I also want to fix few small problems in mod_jk, to allow manual
configuration ( where you specify the handler for *.jsp or something else
using SetHandler ) to completely override mod_jk ( i.e. avoid the double
mapping in apache and jk_uri_worker_map ).

Something like that - easy to parse ( I'm looking at minimal extensions to
the current C configuration code in mod_jk ).

BTW, there is value in having a "uniform" configuration for all servers,
i.e. stop passing config options in server.xml format ( and obj.conf,
registry, ini ), but use the same and

( the value is simpler documentations, simpler code ).

Another value ( for me ) is that it'll allow my other project ( very small
footprint tomcat, without xml parsing and any other big thing - i.e. a
j2me-class runtime ). The "simpler to parse but complete" urimaps can also
be used by standalone embeded tomcat.

I wish :-)

Well, I'll start with the java side and the uriworkermap, which is already
known by mod_jk.

Well, I have 2 full days to work on that ( today and tommorow ), I have a
small vacation ( but only 2 days of it will be for tomcat ).

I'm not working on the autoconf right now, collecting all mappings in java
is the first step.

Form login is the another hard one. Again, as long as we can't handle all
web.xml, I think we must default to forward-only ( and manual mode if
someone wants static files served by apache ).
