Hi,

I am using Squid-2.7.STABLE4 on Gentoo Box. I am trying to cache the youtube's video but not able to do so. I have followed the links
http://www.squid-cache.org/mail-archive/squid-users/200804/0420.html
http://wiki.squid-cache.org/Features/StoreUrlRewrite.
According to these urls I tuned my squid.conf as

acl youtube dstdomain .youtube.com .googlevideo.com .video.google.com .video.google.com.au .rediff.com
acl youtubeip dst 74.125.15.0/24
acl youtubeip dst 208.65.153.253/32
acl youtubeip dst 209.85.173.118/32
acl youtubeip dst 64.15.0.0/16
cache allow all
acl store_rewrite_list dstdomain mt.google.com mt0.google.com mt1.google.com mt2.google.com
acl store_rewrite_list dstdomain mt3.google.com
acl store_rewrite_list dstdomain kh.google.com kh0.google.com kh1.google.com kh2.google.com
acl store_rewrite_list dstdomain kh3.google.com
acl store_rewrite_list dstdomain kh.google.com.au kh0.google.com.au kh1.google.com.au
acl store_rewrite_list dstdomain kh2.google.com.au kh3.google.com.au

acl store_rewrite_list dstdomain .youtube.com .rediff.com .googlevideo.com
storeurl_access allow store_rewrite_list
storeurl_access deny all
storeurl_rewrite_program /usr/local/bin/store_url_rewrite

refresh_pattern . 999999 100% 999999 override-expire override-lastmod ignore-reload ignore-no-cache ignore-private ignore-auth

But when i am accessing any video of Youtube, I always get TCP_MISS/200 in access.log and in store.log
 1226578788.877 RELEASE -1 FFFFFFFF C51CDFBB595CB7105BB2874BE5C3DFB0 303 1226578824 -1 41629446 text/html -1/0 GET http://www.youtube.com/get_video?video_id=tpQjv14-8yE&t=OEgsToPDskKT1_ZEE8QGepXgMQ1i-_eY&el=detailpage&ps=

There are lots of "RELEASE" and very few almost negligible "SWAPOUT" in the logs.
I repeated this exercise many times but always getting the same result that is TCP_MISS/200 in access.log.

Please suggest me am i missing some thing or I need to add some more thing in squid.conf.
