Problems accessing sites with very short DNS lifespan

[M A Young <m.a.young@xxxxxxxxxxxx>]

I have seen a couple of sites where access via squid is very slow. The 
issue seems to be that the time-to-live entry on their DNS record is 10 
seconds in one case, and 30 seconds in another, which I think means that 
squid is rechecking DNS frequently enough to slow things down. I worked 
around one of these by putting entires in /etc/hosts but this isn't very 
scalable. Are there any alternatives to this, perhaps some way of setting 
a minimum timeout for DNS records on squid, so it can cope with these 
strangely configured sites?
