Near the end of 3.9 Soft State section found on
http://docs.racket-lang.org/web-server/stateless.html?q=%23%3Aquit&q=rackunit&q=commandline&q=substring&q=dispatch-rules&q=response/full#(part._stateless-example)
#lang web-server
(provide interface-version start)
(define interface-version 'stateless)
(define softie
(soft-state
(printf "Doing a long computation...\n")
(sleep 1)))
(define (start req)
(soft-state-ref softie)
(printf "Done\n")
(start
(send/suspend
(lambda (k-url)
(response/xexpr
`(html (body (a ([href ,k-url]) "Done"))))))))
$ plt-web-server -p 8080
Doing a long computation...
Done
Done
Done
Done
How does the above command know that it's supposed to execute the code
above it? Is there some convention for this magic to happen?
