A secret technique many web services implement is redirecting mobile devices to a sub-domain containing the alternative mobile version of the site layout.
Note that if your application lives in a sub-domain (for example, foo.example.com), type your base domain in the Base Domain field (that is, example.com).
请注意如果您的应用程序位于子域中（例如，foo.example.com），则请在 Base Domain 字段中键入您的基础域（也就是说，example.com）。
