I've got a public-facing non-web2py website at our root domain (http://ourdomain.com), and a web2py app at a subdomain (http://app.ourdomain.com).
When a user comes to the root site that has a valid logged in session with our app, I'd like to redirect them to the app subdomain automatically. Is there a simple recipe for doing this? I was going to have an IFrame in the main site load a 'check_loggedin' function from the app, and use javascript to redirect the parent window to the app if the user was logged in. But possibly there's an simpler solution using cross-subdomain cookies? --
