Actually, I'd say both are broken. NS4 4.04 crashes as soon as I click Ok
after setting up an automatic proxy.

IE4 doesn't work at all sometimes, and you have to restart the machine to
make it work... and even then it won't work.

Right now, we run this script:

function FindProxyForURL(url, host) {

   // If they have only specified a hostname, go directly.
   if (isPlainHostName(host))
      return "DIRECT";

   // Connect directly to our domain
   if (dnsDomainIs(host, ""))
      return "DIRECT";

   // So the error message "no such host" will appear through the
   // normal Netscape box - less support queries :)
   if (!isResolvable(host))
      return "DIRECT";

   // We only cache http
   // gopher, wais will come after we test it
   if (url.substring(0, 5) == "http:" || url.substring(0, 4) == "ftp:")
      return "PROXY; DIRECT";

   // no matches made, return direct
   return "DIRECT";

It works, but IE4 tends to not work the first time.
