Yeah, ok. So a client to me, for example http://www.stadsnat.se has their DNS set up as such: > host www.stadsnat.se www.stadsnat.se is an alias for cluster.atlascms.se. cluster.atlascms.se has address 94.247.170.170 Now, atlascms.se WAS a wildcard DNS, but isn't any longer. Even so, the requests I get look largely like this: 94.254.41.78 cluster.atlascms.se - [24/May/2013:16:25:24 +0200] "GET /wpad.dat HTTP/1.1" 200 70 "-" "Mozilla/5.0 (compatible; MSIE 10.0; Win32; Trident/6.0)" I.e. a request to that domain name, not to a wpad subdomain. So the wildcard DNS thing doesn't seem to even apply... Or am I mistaken? -- Sandman[.net]
