JW Player Error#2124 for youtube videos

JW Player Error#2124 for youtube videos

I am an ASP.Net developer, i am using JW Player in my site to use videos
directly from youtube. Its working perfectly. But there is an issue, that
when once i disconnect youtube (internet), it don't play video(gives
error#2124 as it should give).But again when i connect youtube (internet)
and play videos, it again(still) shows the same error#2124 until and
unless i don't clear browser's cache.When i clear the cache of browser it
normally play the videos. I don't want to clear cache of browser menually
or programmatically because cache always contains some other important
things too. So please is there any other way, so that when i re-connect
internet, it should normally play rather than to show same error#2124.
Here is my player setup:
jwplayer("myElement").setup({
file: 'http://www.youtube.com/watch?v=' +
myonlyyoutubefilename,
height: 380,
width: 750,
autostart: 'true',
});
//Here 'myElement' is the id of my player's div.
