* Ensure that no user is logged in before proceeding to next route middleware.

|
|
* This middleware ensures that no user is logged in. If a request is received
|
|
* that is authenticated, the request will be redirected to another page (by
|
|
* default to `/`).
|
|
*
|
|
* Options:
|
|
* - `redirectTo` URL to redirect to in logged in, defaults to _/_
|
|
*
|
|
* Examples:
|
|
*
|
|
* app.get('/login',
|
|
* ensureLoggedOut(),
|
|
* function(req, res) { ... });
|
|
*
|
|
* app.get('/login',
|
|
* ensureLoggedOut('/home'),
|
|
* function(req, res) { ... });
|
|
*
|
|
* app.get('/login',
|
|
* ensureLoggedOut({ redirectTo: '/home' }),
|
|
* function(req, res) { ... });
|

|
|
* @param {Object} options
|
|
* @return {Function}
