Hi Amos, Thanks for the reply. I have another query now. If the squid is configured in the transparent mode, a. if a url say yahoo.com is requested through a browser like IE to squid, will the IE itself initiate a DNS lookup before forwarding the request to squid or will it simply forward the request to the squid and let the squid do the DNS look up? Thanks. -Anita -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/DNS-Squid-tree-with-parent-child-tp4573394p4580445.html Sent from the Squid - Users mailing list archive at Nabble.com.
