I'm trying to write a servlet that plugs into the existing server. Here's
an example:
#lang racket
(require web-server/servlet-env)
(require web-server/http/bindings)
(require web-server/http/response-structs)
(require web-server/http/xexpr)
(require racket/sandbox)
(define lazy-eval (make-evaluator 'lazy))
(map lazy-eval
'(
(require web-server/http/bindings)
(require web-server/http/response-structs)
(require web-server/http/xexpr)
(require racket/promise)
(define (lazy-handler request)
(let ((bindings (request-bindings request)))
(if (exists-binding? 'hi bindings)
(response/xexpr "Hi!")
"")))
))
(define (start request)
(force ((lazy-eval 'lazy-handler)
request)))
(serve/servlet start
#:launch-browser? #f
#:quit? #f
#:listen-ip #f
#:servlet-path ""
#:port 8080
#:servlet-regexp #rx"main.*"
#:extra-files-paths
(list (build-path (current-directory) "extraFiles")))
