Dear All,
I know this topic have been around every now and then; but i'm desperate
now in finding any fix.
I tried the configuration as mentioned in this page:
"Caching YouTube Content"
http://wiki.squid-cache.org/ConfigExamples/DynamicContent/YouTube?highlight=%28ConfigExamples%2FIntercept%29|%28ConfigExamples%2FAuthenticate%29|%28ConfigExamples%2FChat%29|%28ConfigExamples%2FStreams%29|%28ConfigExamples%2FReverse%29|%28ConfigExamples%2FStrange%29
But encountered this message in the access.log:
1272165634.722 0 202.79.24.34 TCP_MEM_HIT/302 784 GET
http://v11.nonxt4.c.youtube.com/videoplayback? - NONE/- -
It says TCP_MEM_HIT right at the first time the page is loaded. However,
the YouTube screen on the browser would say "An error occurred, please
try again later".
Please, anyone has any fix to this? Or do i need to apply the patch
given at the bottom of the page?
I am running squid-2.7-stable7 on CentOS with the squid.conf file as below:
