That is what the min-size and max-size parameters of cache_dir are for.

Then try it:

That is *not* an error. It is level-3 debug information. Whatever your
problem was its not that.

Squid is simply testing a URL sub-string to see if it is a raw-IP or a
domain name. No DNS lookup was performed.

FYI: "Name or service not known" is the rather obscure output the OS
produces when a raw-IP test is done.
