As explained previously (see PAS for OpenEdge and Client Interaction), a session-managed client connection to a PAS for OpenEdge instance is in one of two states:
Unbound — Where remote procedure requests over the connection can be handled by any available PAS for OpenEdge session
Bound — Where remote procedure requests over the connection are handled by a single PAS for OpenEdge session that is dedicated to the connection
By default, a session-managed connection is unbound.
