This is the problem that CARP and other consistent hashing approaches
are supposed to solve. Unfortunately, the Squid in the front will
often be a bottleneck...

Hi Pablo
Actually, it is my case.
The URL-hash is helpful to reduce the duplicated
objects. However, once adding/removing squid server,
load balancer needs to re-calculate the hash of URL
which cause lot of TCP_MISS in squid server at the
inital stage.
Do you have same experience ?
Thanks

I dealt with the same problem using a load balancer
in front of the
cache farm, using a URL-HASH algorithm to send the
same url to the
same cache every time. It works great, and also
increases the hit
ratio a lot.

Dear all
At this moment, I have several squid servers for
http
caching. Many duplicated objects have been found
in
different servers. I would minimize to data
storage
by installing a large centralized storage and the
squid servers mount to the storage as data disk.
Have anyone tried this before?
thanks a lot
