What the heck, as long as I'm here already...
I'd say that you want to look at setting up filters to handle the
pre-request action. You can basically catch every request for your site in
a filter, make sure that it is appropriate, that sessions and application
are set-up right, and even do funky model 2 (request.setAttribute) stuff in
there before the actual JSP gets it.
Look at:
<servlet-mapping> and <filter-mapping> in web.xml
http://www.orionserver.com/docs/web.xml.html
That should cover both pre-JSP action and catchall servlet mapping.
The load balancing business is usually pretty implementation specific, so I
don't have much to offer there.
