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
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
acl youtubeip dst
acl youtubeip dst
acl youtubeip dst
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
quick_abort_min -1
##hierarchy_stoplist cgi-bin ?
maximum_object_size_in_memory 1024 KB
cache_dir ufs /var/cache/squid 2000 16 256
maximum_object_size 4194240 KB
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern -i \.flv$ 10080 90% 999999 ignore-no-cache override-expire ignore-private
refresh_pattern get_video\?video_id 10080 90% 999999 ignore-no-cache override-expire ignore-private
refresh_pattern youtube\.com/get_video\? 10080 90% 999999 ignore-no-cache override-expire ignore-private
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=
1226578813.447 SWAPOUT 00 00000314 7CAD15F0E273355B5D18A2B6F8D1871F 200 1226578825 1186657973 1226582425 video/flv 2553595/2553595 GET http://v16.cache.googlevideo.com/get_video?origin=sjc-v176.sjc.youtube.com&video_id=tpQjv14-8yE&ip=
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.
