    Yo All!

    For those following along in the Doc, Foundry calls DSR by the name
    of "Switchback".

    DSR has other problems. They are mentioned in the Foundry doc. For
    one it breaks load balancing since the Server Iron can not tell when
    a connection has ended or timed out. All an SI can do in DSR mode
    is round robin.

    FYI, it looks like the www.foundrynet.com website is down at the moment.
    It has been reported to them. Always best to keep a local copy of
    the doc in cases like this....
