Example -- All clients through two proxy servers for some requests

  function FindProxyForURL(url,host) {
   // If the host requested on the URL line is not a FQDN (eg, it is 'www'),
   // then don't proxy.
    if (isPlainHostName(host)) {
      return "DIRECT";
    }
   
   // Now do the list of IP-restricted services; they go through the proxy
    if (shExpMatch(host, "*eb.com") || shExpMatch(host, "*oclc.org")) {
      return "PROXY proxy1.college.edu:4545; PROXY proxy2.college.edu:4545";
    }
    
   // Otherwise, go directly to the origin server
    return "DIRECT";
  }
