Prepare!

User Ned Kelly noted in the opera.general newsgroup that Opera is blocked from accessing Optus.net.au because of a very version-specific browser sniffer (thanks to Dave Hodgins for his research on this matter). Basically, Opera users can access the Optus website simply by setting a single magic variable (is_opera720up) via a User JavaScript...

Download or view the optusNetAu.js file

[B]if (document.domain.match(/^(www\.)?optus.net(\.au)?$/)) {
   window.opera.defineMagicVariable("is_opera720up",
      function() { return true; },
      null);
}[/B]

Enjoy.
