Can I configure a webapp that is stored on something other than filestore?
I'm working on a virtual learning environment. It's essentially one
huge webapp. We don't want to manage files on the physical filestore;
instead, we want to use our own virtual filestore, for reasons too zany
to go into.
Is there a way of setting eg. an appBase or a docBase so that it points,
not to filestore, but to a URI? If so, we can add an appropriate
handler to the URIs so that we manage vfs:... and everything Just Works.
Failing that, is there another appropriate mechanism for intercepting
filestore access from Tomcat and redirecting it to our own code?
A bit of an open question, I know. The Tomcat 4 documentation appears
to indicate that a Host's appBase is a URL but, on trying it with
5.0.28, file: URLs are not recognised, let alone anything more
outlandish.
All help gratefully received!

Posted by Steve Kirk <to...@web-startup.co.uk>.
I believe that if your servlet is /mywebapp/myServlet and your user accesses
/mywebapp/myServlet/iwant/this/file, the "iwant/this/file" part is available
as the request parameter getPathInfo() and you can do what you like with
that - access a database, access any filesystem to which you have access,
redirect to another URI, etc. So all you need to do is write a simple
servlet that maps their request to whatever resource you want to map it to.
This could include a simple redirect to another URI. Never used this myself
but have noticed it in the docs.
