3.2.5.1.3 Constructing Client Info PDU

  • Article

The Client Info PDU (as specified in [MS-RDPBCGR] section 2.2.1.11) is constructed by the client during the connection establishment phase (as specified in [MS-RDPBCGR] section 3.2.5.3.11).

For remote applications integrated locally (RAIL) clients, the flags field of the Info Packet (as specified in [MS-RDPBCGR] section 2.2.1.11.1.1) MUST have the INFO_RAIL (0x00008000) flag set. This informs the server that the client wants to create a RAIL session.

If the client supports Enhanced RemoteApp, the flags field SHOULD also have the INFO_HIDEF_RAIL_SUPPORTED (0x02000000) flag set. This flag requests that the server create a RAIL session in Enhanced RemoteApp mode. Setting this flag does not guarantee that Enhanced RemoteApp will be enabled since the server may not support this mode.
