    Hi Carl-Uno,

    Point taken - certainly on port 631 you don't get recognized
    as HTTP at all by most infrastructure servers.

    For IPP/1.0 (or later) products that are configurable to use
    port 80 (and many are because they don't pass through firewalls
    at all otherwise), the problems are relevant.

    Cheers,
    - Ira McDonald

    Ira,

    It was suggested in the IETF-IPP meeting that we can probably avoid
    most of these problems by always using port 631.

    Hi folks,

    Interesting recent I-D from IETF Web Replication and
    Caching (WREC) WG:

    "Known HTTP Proxy/Caching Problems"
    <draft-ietf-wrec-known-prob-01.txt> (10 March 2000)

    One of the documented problems is called:

    "Lack of HTTP/1.1 compliance for proxy caches"
