All, I am really sorry i was looking at the access.log file of squid instance that is user facing and not the instance that is doing the fetching/caching and there i can see mp4 files being cached. However i am not very much confident about my settings so please read my queries and the configuration file and advice. I would be really thankful. ---------------------------------------- > From: gigoz@xxxxxxx > To: squid-users@xxxxxxxxxxxxxxx > Date: Fri, 14 May 2010 12:00:46 +0000 > Subject: Dynamic Content Caching/Windowsupdate/Facebook/youtube > > > > Dear All, > > > I require your help and guidance regarding dynamic content caching.

As rewrite_url is not exported in new versions(version 3 and above) of squid is it still possible for squid to cache facebook/youtube videos? Have i configured it correctly?
