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.

Subject: RE: IPP> PRO - New I-D - Known HTTP Proxy/Caching Problems
It was suggested in the IETF-IPP meeting that we can probably avoid
most of these problems by always using port 631.
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"
