3.3.5.2.1 Processing of Bitmap Cache Error PDU

The structure and fields of the Bitmap Cache Error PDU are specified in section 2.2.2.3.1, and the techniques described in [MS-RDPBCGR] section 3.3.5.2 demonstrate how to process the contents of the PDU.

Once this PDU has been processed, the server MUST flush the appropriate Bitmap Cache entries (see section 3.1.1.1.1) and resend the graphics data associated with the affected area.

The server SHOULD honor up to five Bitmap Cache Error PDUs for a given connection; further error PDUs SHOULD be ignored for the duration of the connection to reduce the server overhead.
