IWTSSBPlugin interface (tssbx.h)
[The IWTSSBPlugin interface is not supported after Windows Server 2008 R2. Starting with Windows Server 2012 please use the ITsSbPlugin interface.]
Used to extend the capabilities of Terminal Services Session Broker (TS Session Broker). Implement this interface when you want to provide a plug-in that overrides the redirection logic of TS Session Broker.
Inheritance
The IWTSSBPlugin interface inherits from the IUnknown interface. IWTSSBPlugin also has these types of members:
Methods
The IWTSSBPlugin interface has these methods.
| IWTSSBPlugin::Initialize Initializes the plug-in and returns a value that indicates the redirection capabilities of the plug-in. |
| IWTSSBPlugin::Terminated Notifies the plug-in that it is about to be destroyed by Terminal Services Session Broker (TS�Session Broker). |
| IWTSSBPlugin::WTSSBX_GetMostSuitableServer Returns the ID of the server to which Terminal Services Session Broker (TS�Session Broker) should direct the incoming connection. |
| IWTSSBPlugin::WTSSBX_GetUserExternalSession Redirects an incoming connection to a computing resource, such as a virtual machine, a blade server, or even the user's own corporate desktop by providing a WTSSBX_MACHINE_CONNECT_INFO structure that contains information about the resource. |
| IWTSSBPlugin::WTSSBX_MachineChangeNotification Notifies the plug-in that a change occurred in the server environment. |
| IWTSSBPlugin::WTSSBX_SessionChangeNotification Notifies the plug-in that a change, such as a logon, logoff, disconnect, or reconnect, occurred in the session. |
Remarks
TS Session Broker calls the WTSSBX_GetUserExternalSession method so that the plug-in can direct an incoming connection to a computer that does not belong to a farm in TS Session Broker.
Alternatively, TS Session Broker calls the WTSSBX_GetMostSuitableServer method so that the plug-in can direct an incoming connection to a computer that does belong to a farm in TS Session Broker.
These methods reference an individual server in the farm by using the unique MachineId assigned to the server by TS Session Broker. When a server joins a farm in TS Session Broker, TS Session Broker calls the WTSSBX_MachineChangeNotification method to notify the plug-in of the change and pass the MachineId of the new server to the plug-in.
