Hello all, I'm beginning to implement a Squid setup and am in particular looking to cache Youtube as it is a significant chunk of our traffic and we don't want to outright block it (yet). I'm using squid-2.6.STABLE6 from RHEL 5.1 (latest errata). I've been reading around a lot and am seeking a bit of clarification on the current status of caching youtue and potentially other streaming media. Specifically: * Adrian mentions support for Youtube caching in 2.7 -- which seems to correspond with this changeset: http://www.squid-cache.org/Versions/v2/2.7/changesets/11905.patch Which would seem to be only a configuration file change. Is there any reason Youtube caching won't work correctly in my 2.6 version with a similar setup (and the rewriting script as well I guess)? * If there are additional changes to 2.7 codebase that make youtube caching possible, are they insignificant enough that they could easily be backported to 2.6? I'm trying to decide how I will convince Red Hat to incorporate this as I doubt they'll want to move to 2.7. Alternate of course is to build from source which I am open to. My config file is as follows: http_port 3128 append_domain .esri.com acl apache rep_header Server ^Apache broken_vary_encoding allow apache maximum_object_size 4194240 KB maximum_object_size_in_memory 1024 KB access_log /var/log/squid/access.log squid refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 acl all src 0.0.0.0/0.0.0.0 acl esri src 10.0.0.0/255.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT # Some Youtube ACL's acl youtube dstdomain .youtube.com .googlevideo.com .video.google.com .video.google.com.au acl youtubeip dst 74.125.15.0/24 64.15.0.0/16 cache allow youtube cache allow youtubeip cache allow esri http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localhost http_access allow esri http_access deny all http_reply_access allow all icp_access allow all coredump_dir /var/spool/squid # YouTube options. refresh_pattern -i \.flv$ 10080 90% 999999 ignore-no-cache override-expire ignore-private quick_abort_min -1 KB # This will block other streaming media.

However they are never "HIT" even when the same server is used. I wonder if the refresh_pattern needs to be updated? The GET requests for the video do not have a .flv in their filename.... What does refresh_pattern search for a match? The request URL? The resulting MIME type? That's it for now. :) Thanks in advance. Ray
