Hi to all, I'm using wccp ver2 on a cisco3620 with squid in transparent proxy mode. Everything works fine, but clients connecting windowsupdate site hangs, and squid try to get some .cab files generating up to 2mbit/s traffic. I tryed to create an acl like: acl wup dstdomain v4.windowsupdate.microsoft.com no_cache deny wup In access.log I get TCP_MISS:DIRECT, but squid still hungs. Any suggestions? Thanks in advance, Matteo Tescione RMnet Communications, Rome - Italy
