 * Returns a permission object representing the permission necessary to make the connection represented by this object. This method returns null if no permission is required to make the connection. By default, this method returns   {@code java.security.AllPermission}. Subclasses should override this method and return the permission that best represents the permission required to make a a connection to the URL. For example, a   {@code URLConnection}representing a   {@code file:} URL would return a{@code java.io.FilePermission} object.<p>The permission returned may dependent upon the state of the connection. For example, the permission before connecting may be different from that after connecting. For example, an HTTP sever, say foo.com, may redirect the connection to a different host, say bar.com. Before connecting the permission returned by the connection will represent the permission needed to connect to foo.com, while the permission returned after connecting will be to bar.com. <p>Permissions are generally used for two purposes: to protect caches of objects obtained through URLConnections, and to check the right of a recipient to learn about a particular URL. In the first case, the permission should be obtained <em>after</em> the object has been obtained.

In the second case, the permission should be obtained and tested <em>before</em> connecting.
