/**
 * Specifies the priority of a bean implementation when multiple implementations

 * Higher values indicate higher priority. When multiple implementations of the same

 * Example usage:
 * <pre>

 *
 * As policy, implementations of this interface are responsible for selecting which cookies to
 * accept and which to reject. A reasonable policy is to reject all cookies, though that may
 * interfere with session-based authentication schemes that require cookies.
 *
 * As persistence, implementations of this interface must also provide storage of cookies. Simple
