Re: [squid-users] Alteon + squid

I suppose you are referring to having duplicate objects in the layer 1
squid servers? Is fine actually, since the layer 1 squid dont cache any
objects, just forward requests and replies.

Our concern is to achieve higher hit rate in the layer 2 squid servers.
If it is beneficial, we can further separate the layer 2 squid servers to
smaller clusters to handle specific domain range.
