Config Changes:

Make sure you remove these lines:

#We recommend you to use the following two lines.
acl QUERY urlpath_regex cgi-bin \?
cache deny QUERY

Refresh Patterns:

Places these refresh patterns at the end of your list.

# This pattern works around currently broken If-Modified-Since revalidation behaviour from this
# particular google/youtube URL set.
refresh_pattern ^http:\/\/74\.125       86400 20% 86400 override-expire override-lastmod
# This pattern defaults all content without revalidation/explicit expiry information to
# not be cached; replacing the old "cache deny QUERY" rule. 
refresh_pattern -i (/cgi-bin/|\?) 0  0%  0
refresh_pattern .               0       20%     4320

# store url redirector config

# old-style youtube URL:
# http://sjl-v4.sjl.youtube.com/get_video?video_id=o6iJeypmPbs
acl store_rewrite_list dstdomain .youtube.com


# And now, since the "new style google youtube" videos use a damned IP host, grr!
