 Ok, you mean you are using the dns servers from your isp , but you are
using
 squid's internal dns.

   cachemgr provides access to various stat's presented by the squid
cache.
   Install 'cachemgr' in the cgi-bin directory of an Intranet webserver
   you have access too, and access/use it accordingly.
   See squid.conf.default concerning protecting cachemgr's usage and
   access control.

   On the overall upgrading to SQUID 2.5 (S3) would be recommended,
although
   it is not sure that this will solve this particular problem.
