Vimeo not caching

I am having an issue getting Vimeo to cache videos. YouTube, Google Video and Dailymotion test great. I noticed that Vimeo calls a Javascript to run their videos. I was able to find the video source for Vimeo that links directly to the video. Here is the format link: http://vimeo.com/moogaloop.swf?clip_id=4298315
I do not know what to change in the Squid.conf to make Vimeo cache that format address.
Any help would be greatly appreciated.
