Dear Fellow,
I am implement a Distributed cache system (1 child Proxy, 2 parent proxy as
sibling).
in the cache peer algorithm, I use Weighted Round-Robin.
But when I analyze the log using Squeezer, I am found that there is no hit
requestin the parent proxy.
I have attached the conf (Child.conf, Parent1.conf,Parent2.conf), and the log
analyze
result.
For Simplicity, Just download the Zip file.
I am very pleased that you want to lend your time to help me (Because the
deadline is very close).
Thanks in advance.
