Abstract
A method, system and article of manufacture are disclosed for quiescing multiplexed client messaging conversations. The invention uses plural independent mutexes to stop the application sends from both ends of a client/server channel, while allowing unsolicited control flows from the server to client to also be handled and quiesced. Once the channel is quiesced a channel-wide renegotiation, such as SSL secret key reset, can flow. The channel can then restart, again with the possibility of unsolicited server to client flows. The preferred embodiment of the invention provides a number of important advantages. For example, this embodiment allows channel-wide negotiation flows to occur on a multiplexed channel without the need to wait for application conversations to complete. It also allows channel-wide negotiation flows to occur on a multiplexed channel on which unsolicited server to client flows can occur.
