Hi Amos,
many thanks for your answer.
I would like to deny cache for .flv and .swf file, Could I do that?
Deny the complete youtube and dailymotion could be a solution, BUT
there are
not the only domains that I will have to deny, and if I need to deny
cache
for every video providers, I'll have a lot of job to do.
PS: I'm in my lab domain, I'm testing the 3.2.0.5 version of SQUID.
The way the "cache" access control is currently implemented in Squid it
does not play nice for reply-based non-caching. That needs to be fixed,
but there are other storage and handling problems holding us up.
For now the refresh_pattern can be used to discard non-cacheables based
on URL regex patterns. Sadly *after* they are already on disk. Just set
the three time parameters to "0 0% 0" with a lot of the override-*
options.
You could also try setting a maximum object size on disk cached
objects, flv/swf videos tend to be 2MB-50MB.
FWIW: You have not actually said it but I get the impression you are
struggling with speed problems handling the videos flowing through, yes?
All of the Squid-3.x have shown slowdowns whether caching was enabled or
not.

Hi folks,
I'm still dealing with some WCCP special question.
All my Cisco's and squid stuffs are working well, Cisco is
redirecting
requests, and squid do the job.
BUT I'm wondering me if the following rules are correct and able to
be
respected with the wccp protocol active on squid.
acl streaming_media_rep rep_mime_type ^video/x-flv
acl streaming_media_req req_mime_type ^video/x-flv
cache deny streaming_media_rep
cache deny streaming_media_req
I'm trying to not cache youtube or dailymotion streams at all, but
unfortunatly it seems to not be really efficent.
As you can see below, squid is still handeling the flux:
Is there someone who now, how to avoid youtube's video to be
cached?
Caching descisions are made on the request details. So mime type is
too
late to work. Catching the User-Agent should work until they upgrade
YT away
from flash ...
acl flash browser Flash
cache deny flash
And of course the YT domains can be non-cached as a whole with
dstdomain.
