anchor.diff:  * (WPAD) Proxy Script. If the user’s proxy configuration is “Automatically detect settings” or “Use automatic configuration script” inside Tools > Internet Options > Connections > LAN Settings, the browser will run the FindProxyForUrl function in the specified WPAD proxy configuration script to determine which proxy should be used for each request. If the script returns "DIRECT", the browser will bypass the proxy and the site will be mapped into the Local Intranet Zone. When mapping a URL to a Zone, URLMon will call the FindProxyForUrl function to determine if the bypass rule applies. One interesting twist is that the proxy script may itself call dnsResolve to get a site’s IP address and use that information as a part of its determination.

  Instead, determination that a site belongs to the _Local Intranet Zone_ is based on a number of rules:

  * Direct Mapping. As with other Zones, users or network admins may map a list of URL patterns into the Local Intranet Zone. This list is viewable by clicking Tools > Internet Options > Security >  Local Intranet > Sites > Advanced.
  * The PlainHostName rule (aka "The Dot rule"). If the URI’s hostname doesn’t contain any periods (e.g. http://team/) then it is mapped to the Local Intranet Zone.
