I've put up the acl for them and yet everything else gets a hit except the
flash media itself.

config :

# TAG: Caching Dynamic Contents
acl youtube dstdomain .youtube.com
acl googlevideo dstdomain .google.com .googlevideo.com
cache allow youtube
cache allow googlevideo

# TAG: hierarchy_stoplist
# A list of words which, if found in a URL, cause the object to
# be handled directly by this cache. In other words, use this
# to not query neighbor caches for certain objects. You may
# list this option multiple times. Note: never_direct overrides
# this option.
#We recommend you to use at least the following line.
hierarchy_stoplist cgi-bin ?

# TAG: cache
# A list of ACL elements which, if matched, cause the request to
# not be satisfied from the cache and the reply to not be cached.
# In other words, use this to force certain objects to never be
cached.
#
# You must use the word 'DENY' to indicate the ACL names which
should
# NOT be cached.
#
# Default is to allow all to be cached
#We recommend you to use the following two lines.
acl QUERY urlpath_regex cgi-bin \?
no_cache deny QUERY
#cache deny QUERY

access.log on second viewing of same media url :
