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,
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"
