Gets the maxAge setting.

When making a preflight request the client has to perform two request with can be inefficient. This setting enables the caching of the preflight response for the specified time. During this time no preflight request will be made.

Returns:

long the time in seconds that a preflight request may be cached.

Returns the allowed set of Request Methods.
