This plugin will add a field to users’ profiles specifically for redirecting the user upon a successful login. If no redirect is specified the standard login rules will apply. It doesn’t currently support bulk redirects as in the instance of redirecting users with a specific role. Simple Login Redirect does support local redirects and redirects that point to another site.
