Right -- one of the requirements for this is that we have a match system
that is fast. This one's speed is faster for shorter paths, slower for
longer paths, and much faster than doing a full regex check.

Yes -- the simple code was a bit too simplistic. (I *had* just woke up..
:)

Yes -- definitely... And the remaining ext should not contain a '/'
character because that is a significant separator. You get quibble bonus
points.. :)

the latter is how I'd see it best happen. JSP's primary interactive
mechanism will be parameters. If you need to do things based on path
info, then you really should be writing a full servlet and not a JSP.
