My bad... I did not realize that the ICP_QUERY URL should have been the apache IPs and not the squids IPs... I was accessing directly my squids instead of using them as transparent proxies. Once setup as proxies in my browser, I get: ICP_QUERY http://127.0.0.1/img/apache_header.gif which will match for all squids. I still have the GET internal://pc-03/squid-internal-periodic/store_digest "problem" though.. JD
