James,
I even tried the examples you gave me:
(defroutes main-routes
(GET "/" [] (welcome))
(GET "/form" [] (render-form))
(GET "/login/" [] (login-view))
; (POST "/login/" {request :request params :params} (login-
controller request params))
(POST "/login/" {params :params session :session} (login-
controller params session))
; (ANY "/logout/" [] (logout-controller session))
(ANY "/page/" {request :request session :session} (page request
session "hello" "world"))
(GET "/a" [] (ooops))
(GET "/set" [x :as {session :session}]
{:session (assoc session :x "Shree")
:body (str "You set x = " x)})
(GET "/get" {session :session}
(str "x = " (:x session)))
(POST "/form" {params :params} (handle-form params))
(route/not-found (page_not_found)))
But for WHATEVER reason, the sessions are NOT getting stored? When I
goto the set page, I get:
http://localhost:3000/set
You set x =
-and-
http://localhost:3000/get
x =
respectively. I must REALLY be messing SOMETHING up at my end??? Why
else would this NOT be working???
Thanks,
shree
