• A new class [java.net.URLPermission](../../../api/java/net/URLPermission.html) has been added. URLPermission represents a permission for accessing a resource (or set of resources) defined by a given URL, and for a given set of user-settable request methods and request headers.

• The jdk.net package has been added that contains platform specific socket options and a mechanism for setting these options on all of the standard socket types. The socket options are defined in jdk.net.ExtendedSocketOptionsand the first one to be defined is SO_FLOW_SLA, which is an option for establishing socket flows for multitennant applications. The class jdk.net.Socketsprovides the mechanism for setting and getting these extended options.

• In class [HttpURLConnection](../../../api/java/net/HttpURLConnection.html), if a security manager is installed, and if a method is called which results in an attempt to open a connection, the caller must possess either:

  • a "connect" [SocketPermission](../../../api/java/net/SocketPermission.html) to the host/port combination of the destination URL or
  • a [URLPermission](../../../api/java/net/URLPermission.html)that permits this request.

If automatic redirection is enabled, and this request is redirected to another destination, then the caller must also have permission to connect to the redirected host/URL.
