RE: [squid-users] Dynamic Content Caching/Windowsupdate/Facebook/youtube

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.

I am confused that if connect methods are to be duplicate on both of the instances or i have configured it right specially in perspective of windows update.
