Is it possible to force youtube to clear its cache for a specific playlist

[BlackJack]

in a web project, i want to display all the videos contained in a playlist. I'm using this link with the playlist id \[code\]http://gdata.youtube.com/feeds/api/playlists/PL170E795D5377932F?v=2\[/code\]then \[code\]$sxml = simplexml_load_file($feedURL);\[/code\]recently, two videos got removed from the playlist and my problem is i still have the video informations of both videos in the link above.I think it has something to do with the youtube cache, is there any chance to force youtube to clear it ?thanks
