The initial connection supplied by the user * 2. The settings sent from client or server during capability exchange * 3. The settings merged from the capability exchange and the initial configuration. * * The lifetime of the settings is as follows: * 1. Initial configuration is saved and will be valid for the whole application lifecycle * 2. The client or server settings from the other end are valid from capability exchange until the * connection is ended (disconnect/redirect/...) * 3. The merged settings are created from the initial configuration and server settings and have * the same lifetime, until the connection ends * * * So, when accessing the settings always ensure to know which one you are operating on!
