Thanks Jay. Worked like a charm. For anyone else fighting with the same issue, the only change needed is the `#lang web-server` in-place of `#lang racket` in the code sample - `#:stateless? #t` is already there.
Out of curiosity, since I didn't need to make any code changes to make stateless work, is there any reason to run stateful servlets? The only concern I see is the default stuffer which does disk writes - that too if the urls are large. Nothing a fast disk and short ulrs can't mitigate.
