3.2.5.13.1 Processing of the Server Redirection PDUs
An overview of the principles behind server redirection and an example of how it operates within the context of an RDP connection is presented in section 1.3.3.
Two variants of the Server Redirection PDU can be received by the client to indicate that it MUST terminate the current connection and reconnect to another server. The Standard Security variant (section 2.2.13.2.1) of the Server Redirection PDU MUST be received when Enhanced RDP Security (section 5.4) is not in effect. When Enhanced RDP Security is being used to secure the connection, the Enhanced Security variant (section 2.2.13.3.1) of the PDU MUST be received.
The actual contents of the Server Redirection PDU (embedded in the Standard Security or Enhanced Security variant) are contained in a Server Redirection Packet (section 2.2.13.1). The information required by the client to connect to a new target server MUST be specified in this PDU.
The techniques described in section 3.2.5.2 describe how to process the two variants of this PDU (the instructions regarding the Share Data Header MUST be ignored because it is not present in either PDU).
Once the client has completed processing the appropriate variant of this PDU, it MUST terminate the current connection to the server that transmitted the PDU and initiate a new connection to the target server specified in the Server Redirection Packet.
