[racket] web-server weird K-URL generation when stuffer is used

Here is the background.

I have been running a stateless web-server fine for a while. (Call
this A) It gets started from http://...com/xapps/A and then it
generates various K-URLs as /xapps/A;(( ...))

I just finished developing another 'servlet'  and added to the above
server. (Call this B) It gets started from http://...com/B and then it
should generate K-URLs as /xapps/B;((...))

But it does this

http://..com/xapps/A;((%22k%22%20.%20%22(1%202%2080634528)%22))

A and B does NOT know each other. So why would embed/url in B would
use "A" that it does not know?


Puzzled,
