Sorry, longest match wins for URI matching once the webapp has been
selected. The webapp is selected using the left-most part of the path,
with ROOT being the fall-through case: if you have /foo deployed and
/foo in ROOT, I would expect your /foo webapp to receive the request.
It's clear that's happening even from your failure cases.

No, the webapp is selected first, then the path is trimmed (if
necessary) and then the longest-match wins when matching against
url-patterns configured in that webapp's web.xml.

It's not really clear to me from the spec what to do about a "stopped"
webapp that is still technically deployed. I'm not sure if Tomcat
differentiates between a stopped webapp deployed to /foo and no webapp
at all for /foo. There was a recent bugfix to TC 7[1] to fix something
related, but that was during redeployment and I suspect that if the
webapp is stopped you'd get some other behavior. I tend not to stop
webapps so I've never bothered to play around with it.

No, this is definitely the place to have this discussion.
