Sorry, but that doesn't answer the question of why you/he doesn't
want it to be cached. If he's trying to protect the videos from
being copied then you're going to need to make it clear to him that
you can't stop that from happening without DRM which is a whole
other kettle of fish and usually not worth it.
Aside from that I'm not aware of anything else you can do to stop
clients caching your content. At the end of the day you have no
reliable control over what happens after the data leaves the server.

Caching is one thing, but viewing the video is another -- unless I am mistaken.
While it's true that you have no control over the video file once it
leaves the server, however, what the file does in a foreign
environment is something else.
Typically, DRM schemes are needed when someone wants to protect
digital media from being copied to play in standard players. But, if
you want to restrict playing a video to just your site, then that's
another matter.
One can place actionscript in the video that will stop it from
playing if certain conditions are not met. For example, you can have
a file that exits in your site, but no where else. If the video is
downloaded and an attempt is made to play it, then the video simply
looks for the companion file and if it's not there, then it won't
play.
Is this not true?
Cheers,
