accessing query string parameters?

[alanz]

If I have

(defun on-page1 (body)
  (create-div body :content "You are in on-page1")
  (run body))

(set-on-new-window #'on-page1 :path "/page1")

and I want to process something like "/page1?id=3" (or "/page1/3").

How would I extract the id parameter for a value of 3?

And to answer my own question,

(defun on-page1 (body)
  (let ((params (form-get-data body)))
    (log-console (window body) "A message in the browser's log")
    (create-div body :content params)
    (create-div body :content (format nil "yourname = ~A"
                                      params)))
  (run body))

does the job

Aha! Thanks for that. I'm about to do the same thing.
