Re: New Use Case for W3C WSC

More out of curiosity than anything else, here are two links that should be
embedded in your email. They are safe to click (it's even valid XHTML 1.0!),
one of them is plain HTTP and one is HTTPS (valid SSL certificate, not EV).

http version <http://www.ifette.net/dan.html>

https version <https://www.ifette.net/dan.html>

I'm curious to know if either presents problems...

(And PHB, if you're reading this and want to give me an EV cert to play
around with... ;-)
