1st all of that , this is just a sample and there are alot of samples
similar to it :)
Q1- what does this mean ??? does that mean that error occured on client
side ?? was it dispertion in watching video or hanging in watching video
??
It means the client fetched one request and requested the connection
keep-alive.
Then the client did not use the connection until Squid timed out waiting.
Q2- does this a harmful issue ? does squid affect youtube ??
It is only harmful in that the client connection was holding the socket
resources for the timeout period needlessly.
Q3- if im not caching youtube videos , why should i allow youtube traffic
to go to squid ??? is it better for me to deny youtube traffic from being
injected in squid ??
Perhapse because your users are requesting it. Squid is a HTTP
optimizing proxy not just a cache.
