Hi All again, I've been following the config examples on the Squid Web site: http://wiki.squid-cache.org/ConfigExamples/DynamicContent/YouTube http://wiki.squid-cache.org/ConfigExamples/DynamicContent/YouTube/Discussion I can say it works great. I've been using Squid for quite a while now and had always wanted to be able to cache Youbue videos but could not until I read the above 2 links. However, I still encounter this error message in Cache log such as this one: 2008/12/03 15:49:07| clientCacheHit: request has store_url 'http://video-srv.youtube.com.SQUIDINTERNAL/get_video?video_id=FC4E946i6aE'; mem object in hit has mis-matched url 'http://chi-v249.chi.youtube.com/get_video?video_id=FC4E946i6aE&ip=202.79.29.2&signature=615BA17FC5B6A9B22724204532BA756082C2A57B.1264B3777118E945D75D8653BEBDAABE375B89E3&sver=2&expire=1228315101&key=yt4&ipbits=0'! ... Could someone explain what it means? I'm greatful for any idea or pointer to a workaround. I also read the thread in this list on this for a workaround by Horacio with his great PHP script but that did not work for me either. Any more hints would be much appreciated. Regards, Khem
