I have a long PAC file. The browser(s) (IE and Chrome) are configured to use it and it generally does what it says on the tin. I have a domain that continues to go through the proxy although it should be going direct.

  // Match specific hosts and IPs entered as hosts
  if (buncha stuff ||                   
    shExpMatch(host,"(*.newmarketinc.com)") || 
    shExpMatch(host,"(newmarketinc.com)") || 
    buncha stuff
    )
      return "DIRECT";

Pactester shows that anything in the domain should be direct.

h:\pacparser\pactester.exe -p h:\pacfile -u http://daas.newmarketinc.com

DIRECT

But we continue to pass traffic to hosts in this domain via the proxy. Wireshark and Fiddler both show this.

How do i figure out how my browser has gotten brain-damage? Traffic to other sites in this stanza does properly go direct, as confirmed by Fiddler and Wireshark.
