Microsoft Chat Server SDK Reference

IsUpLink Property

This property contains the flag that determines whether this server will request state information from the other.

Syntax

Flag = ChatPortal.IsUpLink
ChatPortal.IsUpLink = Flag

Parameters

Flag
True if this computer will request state information, False if not.

Remarks

An uplink server will initiate a connection to the chat server at the other end of the portal to acquire that server's state information. The state information includes the server's persistent and dynamic channels and their membership, users currently logged on to the service, and any access restrictions that are in effect, such as user bans.

State information must travel in only one direction over a portal connection; that is, only one server can initiate the uplink. This prevents loops, or circuits, in a network of two or more chat servers. If both computers are uplinks, or if neither computer is an uplink, the connection will not initialize properly.
