i tried with mimimum_direct_hops set to 20 & minimum_direct_rtt set to
250 & squid was build with enable-icmp, .. but when i used tcpdump i saw
that still for www.fooo.com it was quering/fetching from sibling though
www.foo.com is just 8 hops away !

we want to do destination based routing for user squid on our linux
box.. again the aim was to take specific routes for nearby network **for
user squid**,.. we have applied julian patched with iproute to achieve
source ip based policy routing but couldnt acheive the same for user
based policy routing.. i have put this kind of scenario on lartc mailing
list too but not with encoraging replies..

if the 2nd point is achievable then we wont neet rtt & direct_hops as we
can manupulate the routing based owner of the packets, which is not
possible with rtt & direct_hops !

one more point to ask to this list :
of your expereinces, what is the permissable numbers threads one should
allow squid to open for aufs type of cache directory !
we have build squid with **24** threads on redhat 7.3, kernel 2.4.19 &
squid 25s1 on p-III 800mhz & 768mb ram !
