The TS_BITMAPCACHE_PERSISTENT_LIST_PDU structure contains a list of cached bitmap keys saved from Cache Bitmap (Revision 2) Orders (see [MS-RDPEGDI] section 2.2.2.3.1.2.3) which were sent in previous sessions. By including a key in the Persistent Key List PDU Data the client indicates to the server that it has a local copy of the bitmap associated with the key, which implies that the server does not need to retransmit the bitmap to the client (for more details about the Persistent Bitmap Cache, see [MS-RDPEGDI] section 3.1.1.1.1). The bitmap keys can be sent in more than one Persistent Key List PDU, with each PDU being marked using flags in the bBitMask field.
