Yes I would be interested in some data as well.

However, I guess that problem can be easily fixed, as you could just always send two RSTs (first the one with the payload and then one without in case the first one gets lost). Still would be interesting to get a feeling if that actually is a problem that needs fixing.

    Hi,

    have there been experiments on the middlebox traversal properties of RST segments with payloads?

    (Because if they got dropped, the peer would retry the failed connection for potentially much longer.)

    Thanks,
