Wait: I don't understand. I do 'racket main.rkt'. That file contains a call to serve/servlet (with #:stateless? #t) and passes a function 'start' that gets called with requests. I think that maybe what you're saying below is that what I'm doing is not "servlets" and what happens is just what I would expect: there is no fancy monkey business with namespaces (unless my code does it).
Is that right? Robby On Fri, Mar 16, 2012 at 9:22 AM, Jay McCarthy <[email protected]> wrote: > Servlets do *not* share the same module instantiations. Each is in a > different unique one.
