I think I understand, how would I properly log someone out of the
normal GUI, ie when using (app) et al, setting *SesId to NIL maybe? I
just browsed http.l and noticed that variable.

Currently I'm using the following to determine whether the session has
timed out or not:

(de getUsr ()
   (db 'uid '+User (cdr (assoc 'uid *Cookies))))

(de usrQuit ()
  (let Usr (getUsr)
     (or Usr (redir "@logout"))))

So the following redirects to logout if the user id is not in a cookie:

(de logout ()
   (setq *Cookies NIL)
   (cookie 'uid NIL)
   (redir "@start"))

The cookie clearing is probably unnecessary come to think about it in
this case, I might as well just redirect to the start function.

Anyway, everything should start with the start function:

(de start () (if (getUsr) (desktop) (signin)))

Which in my case of course redirected to the signin function:

(de signin ()
      (html 0 "RSS Reader" *Css NIL
         (form NIL
            (<table> NIL NIL NIL
               (<row> NIL "Username"  (gui 'uname '(+TextField) 10))
               (<row> NIL "Password"  (gui 'pwd   '(+PwField)   10))
               (<row> NIL
                  (gui '(+Button) "Login"
                     '(let Uid (chkLogin (val> (: home uname)) (val>
(: home pwd)))
                         (if Uid
                               (cookie 'uid Uid)
                               (setq *Cookies (cons 'uid Uid))
                            (err "Could not login.")))))
               (<row> NIL (<href> "Sign Up" "@register")))))))

It was after pressing the Login button here I got the problem,
redirecting to, and rendering the login form was not a problem.
