flash makes 2 requests and is not cached

i use the jwplayer (player.swf) as flash fallback (object) in the video tag. I have two videos on the site and wonder if its normal that i have two http requests even the player.swf is the same.

Then the other thing is that the player.swf is not cached - I don't get a 304. But the expires header is one month in the future.
