[racket] More on K-URL question

I think the previously asked behavior has nothing to do with stateful
vs stateless.

I've been trying to compose different 'apps' together under one
web-server. /xapps/A, /xapps/B, etc.

I am just realizing that if I happened to use /xapps/B;((
...k-url...)) first then later K-URLs start with /xapps/B; despite the
fact that I am causing K-URLs under /xapps/A.

It seems that I have to run multiple instances of webserver and do
something like

/A reverse proxy to localhost:8080/A
/B reverse proxy to localhost:8081/B


Am I missing something?

PS: I guess the fundamental question is, how to design web-apps that
have many unrelated tasks running under the one instance?
