Can youtube be cached?
Theoretically, it probably could. There are sites like keepvid.com where
you can enter the URL of a video on YouTube (or Google Video, or a bunch
of others), they dig through the HTML and the embedded Flash goo, and
give you a link to download the .flv file. (Then you can go download a
specialized FLV player, and watch your YouTube clips at your
convenience.) Ultimately, it's just another file you download from a Web
server; YouTube's Flash player is just smart enough to start playing the
file before it's completely downloaded.
Of course, those .flv files are about 2MB per minute of video, give or
take a bit. If you're using something like Squid, or the implementation
of Squid built into Mikrotik RouterOS, files that large probably aren't
cached by default, mostly because for smaller sites the odds of multiple
users downloading the same really big file at the same time are usually
fairly small.
