Internet Explorer disallows username:password in URLs due to phishing, or so I recall.  I tried your example with IE8 and it didn't work.  Worked great in FF3.6 with JavaScript disabled.  Might be something to use as a fallback method when JavaScript is disabled and the user is using FF or another compatible browser.
