Hi!
What is happening here? Why does Squid load exactly the same files multiple
times? The effect ist, that the byte hit ratio goes high into the negative
(around -200 or -300 %). How can I prevent this situation? Please help!
Look at this and watch out for the different downloads of those *.mpg files:
And afterward you can see a byte hit ratio of -423 %. What the hell is
this??? I thought Squid should save bandwith. But it seems to waste
bandwith. Please note, that a) there are no other neighbouring caches, and
b) the bandwith waste is reality, I can confirm it with measurements on the
routers.
