Replying a bit late to this...
One interesting thing that the Flash player will do is that if it
finds itself unable to connect directly on 1935, 80, or 443 (for a
site, that, let's say, is blocking 1935 and proxying 80/443 with
squid), it will attempt to tunnel RTMP data inside HTTP GETs and
POSTs. Squid will proxy these - I've tested it myself - but I don't
know what sort of patterns there might be that can be used by squid to
recognize those streams and apply delay pools to them. I suggest
TCPdumping to see if there's something in the headers to match on.

Adobe people don't really know much about it and I can't get to the
Developers. When I call Adobe and ask about RTMP, I get shuffled
around to just about every department.
There is Red5, an Open Source reverse engineering project out there
who may have someone that has more info:

- http://osflash.org/red5 <-- OS Project
- http://swik.net/RTMP <-- Refers to Red5 again
I was hoping it was RTSP-like because it is related to streaming but
from what I can tell, it is not really that similar.

Thank you. Assuming the protocol spec is accurate:
http://osflash.org/documentation/rtmp
The protocol port is NOT 80 or 443. But apparently 1935. And like
other
streams would require a proprietary or hacked client software to
interpret.
If you want to proxy it you should look for a general-purpose proxy
or SOCKS.
If you want to lock it set port 1935 into your firewall.

RTMP is Adobe's protocol used for streaming. As Amos says, RTMP !=
HTTP but it is going to be delivered over Ports 80 & 443, as you
have
already seen. Adobe Flash Media Server contains a caching
component,
I believe, so if you control the content, you might want to look
into
that (rather expensive) option.

Dear all
I have setup squid with delay pools , but some user using rtmp
protocol and using port 443 port for download file .flv
I try to see in access.log but nothing recorder , how come ...?
so my question how to make rtmp protocol to join in delay
pools or
should i forward rtmp protocol to squid ?
Thank's
HTTP != RTMP.
Squid is NOT a general-purpose proxy. It is a WEB proxy.
