Hi everyone... Been a long time since I posted here, but here I am. :)

I'm using squid 2.3Stable4 and am having seamingly random DNS issues. I
checked the 2.3 BUGS page, and the exact problem I am seeing seems to
have been reported and fixed back in 2.3stable2. I have tried both the
internal DNS and external DNS methods of address resolution for squid,
and this still happens. The sites seem to be random, and I can do an
nslookup at my dns server immediately following one of these errors and
the address does resolve. Also, simply turning OFF the proxy cache in
netscape/ie etc, the site can be reached. Re-enabling it gives the same
error. (I even lowered the negative-dns-ttl and negative-ttl options to
see if that would help) no change.

Here is the error page (I am sure you already know what this one looks

The requested URL could not be retrieved

While trying to retrieve the URL: http://www.hotmail.com/

The following error was encountered:
Unable to determine IP address from host name for www.hotmail.com

The dnsserver returned:
DNS Domain 'www.hotmail.com' is invalid: Valid name, no data record of
requested type.

This means that:

The cache was not able to resolve the hostname presented in the URL.
  Check if the address is correct.

Your cache administrator is...


Thanks for any help/ideas regarding this.
