[plt-scheme] post-pure-port

Hi,

I'm having a problem using post-pure-port.

In the program listed below the bindings args are coming through as 

((first-name . Albert;last-name=Einstein;birthday-buttton=...))

to object-test.ss.

Any ideas?

Many thanks!

Cheers,
David


(require (lib "url.ss" "net")
         (lib "cgi.ss" "net")
         (lib "uri-codec.ss" "net"))

(define the-url (string->url "http://bach/cgi-bin/object-test.ss"))

(define the-args (alist->form-urlencoded (list (cons 'first-name "Albert") (cons 'last-name "Einstein")
					                      (cons 'birthday-buttton "..."))))
(define the-port (post-pure-port
                  the-url
                  (string->bytes/utf-8 the-args)
                  (list "Content-Type: application/x-www-form-urlencoded")))
