    // This will prevent the throttle from being layered on top of the OFS; to keep backward
    // compatibility with old configurations, we do not cause the server to fail.
    //
    // Originally, XrdThrottle was used as an OFS because the loadshed code required the ability
    // to redirect the client to a different server.  This is rarely (never?) used in practice.
    // By putting the throttle in the OSS, we benefit from the fact the OFS has first run the
    // authorization code and has made a user name available for fairshare of the throttle.
