Return a HTTP redirect response. So for example, you could do:

  (GET "/user/:id" [id]
{:status 302
 :headers {"Location" (str "/index.html?user=" id)}
 :body nil})

For convenience, Ring has the ring.util.response/redirect function to make
this more concise:

  (GET "/user/:id" [id]
(redirect (str "/index.html?user=" id)))

The same way you interpret route parameters, but you'll need to add the
ring.middleware.params/wrap-params middleware to your handler.

compojure/http-kit redirection

[JvJ]

Hi, I'm starting a web app with compojure and http-kit.  I would like to 
have one request redirect to another page, but I'm not sure how:

(defroutes app
  (GET "/ws" ws-handler) ; Websocket connection
  (GET "/user/:id" [id] ;; I want to redirect to index.html?user=id
   )
  (resources "/"))


When I get the /user/:id path, I would like to return index.html?user=id. 
 How can that be done?


Also, how to I interpret URL params using defroutes?


Thanks.
