I know I can set the status to 3xx to get the browser to immediately load a target, and I can use <meta http-equiv="refresh" content="5;URL='http://www.example.com/'" />
to load after a period of time, but is there a better way? ShowURL seems obvious, but I don’t have a control/session available at this point to use that mechanism.
Use the 301 or a 302 redirect. It’ll save your app the time and resources of creating a session.
