RE: [squid-users] errors while opening sites

Remy,

I'm using /etc/resolv.conf file & have two entries in it.

like

nameserver 10.0.0.1
nameserver 10.0.0.2

& tried to check the time host which is somewhere in the range of 48-50, which seems reasonably o.k.

I'm also using the default cache size, which I want to increase to some extend.
But I'm sure this is not a cache issue.

Its surely something related to DNS name resolution problem.
