Hello, I'm seeing exactly the same problem as was described in this email (in 2004): * http://www.squid-cache.org/mail-archive/squid-dev/200407/0008.html The http client does a DNS lookup, then Squid repeats the DNS lookup and receives a different host IP - which means that Squid makes it's proxy request to a different IP than the original request. Our theory is that the WCCP router redirects the response to the wrong Squid. Anyone else seen the same problem? Anyone got a work around? In that mailing list thread, Henrik had suggested that someone needs to submit a patch to allow Squid to connect to the same IP address as the client connection, but I can't tell if anyone has done this yet. Look forward to hearing from anyone with answers. Squid 2.7 STABLE6 -RichardW.
