Indicates to the server that this client connection is to a slave server, rather than a user.
This command is intended for use in separating connections to single users from those to subsidiary ("slave") servers. It may be used to indicate that priority should therefore be given to requests from this client, as it is presumably serving more than one person. It might also be used to determine which connections to close when system load levels are exceeded, perhaps giving preference to slave servers. The actual use this command is put to is entirely implementation dependent, and may vary from one host to another. In NNTP servers which do not give priority to slave servers, this command must nonetheless be recognized and acknowledged.
