What bothers me about this solution, is that the frequency will be defined in each consumer, whereas a single rate can be defined for the provider. This may looks a bit strange, but I will implement it this way if there is no other mean to set the provider frequency. > Best regards, > Krzysztof > Best regards Olivier
