> Hi,
> example 4 from section 3.6.5 of the Dispatch Router book seems to be incorrect in that it suggests that the *maxSessionWindow* can be used to set the number of frames that can be buffered unsettled. However, from a recent discussion on the mailing list [1], my understanding is that *maxSessionWindow* needs to be set to the total number of bytes that can be buffered, i.e. maxSessionWindow = maxFrameSize * number of frames to buffer.
> Section 4.4.3 on configuring listeners actually describes how *maxSessionFrames* can be used to set the maximum number of frames to buffer in a session. To me this is the more user friendly approach (since it leaves the calculations to the machine) and should be adopted in the policy definition as well.
