3.2.5.1.2.1.4 Processing of Cache Glyph (Revision 1)

The structure and fields of the Cache Glyph (Revision 1) Secondary Drawing Order are specified in section 2.2.2.2.1.2.5. The order fields MUST be processed in accordance with this description.

If the client does not support glyph caching (specified in the Glyph Cache Capability Set described in [MS-RDPBCGR] section 2.2.7.1.8) or the GlyphIndex (section 2.2.2.2.1.2.5), FastIndex (section 2.2.2.2.1.1.2.14), and FastGlyph (section 2.2.2.2.1.1.2.15) Primary Drawing Orders, this order SHOULD be ignored. Furthermore, if a client encounters any inconsistencies or errors when decoding and processing the Cache Glyph (Revision 1) Secondary Drawing Order, the connection SHOULD be dropped.
