MRF Bidirectional Persistence makes assumptions when determining the direction to forward a message that matches a persistence entry. For some systems, the algorithm used forwards the message to the wrong endpoint.


Messages from the server or an alternate server are not identified as needing to be forwarded to the client. Instead they are incorrectly forwarded to back to the server.


-- Using MRF Bidirectional Persistence. -- The system is attempting to forward a message that matches a persistence entry.


None. This is an improvement.

Fix Information

A new iRule command has been added to enable you to specify the direction of travel for the message if a persistence record is found.
