Contexts: can there be a hierarchy?
Ladies and Gentlemen:
Suppose we have a Tomcat 8 server, "https://xyz.example" for argument's
sake, running on Debian (with all of the weird, decentralized file
locations that entails).
Is there a way to set up contexts in a hierarchy, such that requests for
"https://xyz.example/foo/ham," "https://xyz.example/foo/spam," and
"https://xyz.example/foo/eggs" go to distinct webapp contexts?

Thanks. That answers my question.
The important thing is that it's a hierarchy from the URL construction
point of view (e.g., for purposes of path rules directing traffic to the
correct back-end of a load balancer). That it's not a hierarchy in the
file system is irrelevant.

Reading that I understand what you have pointed out and of course fully agree to it :)

It's a hierarchy for the URLs, but not from a webapp location, construction,
or execution perspective - /foo/bar is completely independent of /foo, not
inside or a subset of it.

Dear Chales (and James)
why do you call it not really a hierachy? If you name the deployments e.g.
ROOT.war
foo.war
foo#bar.war
then the "expected" will happen: The longest context path will match to the corresponding container:
* all /foo/bar{,/.*} will be served by foo#bar.war,
* all other /foo{,/.*} will be servered by foo.war
* all other {,.*} will be served by ROOT.war
@James: This will even work with Tomcat 6 ;)
Greetings
Guido

Let's hope that's Tomcat 8.5, since 8.0 has reached EOL.

Not really a hierarchy, but just name your .war files (or directories)
appropriately:
foo#ham[.war]
foo#eggs[.war]
