    Alex,

      I believe this is an enhancement in the AOS roadmap (the name of WebOS on
    the Alteon Application Switch), but don't know the details.

    Regards,

    Ken

    ahhh...distant bells are ringing on this one. I believe we had a similar
    problem before that was caused by exactly the same thing AOL pipelining
    requests.

    I'll investigate this route and let you know how I get on.

    No info on whether re-splicing based on cookie is a feature to be added at
    some point?

    Many thanks,
    Alex
