Web Browser ability to correctly handle standards.

Browsers that have pased Acid3 (version numbers indicate a public release)

Desktop:

Safari 4.0.2
Google
Opera

Mobile:

Iris Browser 1.1.7
Opera Mobile

Microsoft is not interested in passing. "...we are focused on the most important features and standards to make web developers' lives easier. The ACID3 test does not map directly to that goal." - microsoft.com

I may have to configure my server to deny all Microsoft browser users. At least for a while.

The test: http://acid3.acidtests.org/

How to deny access to your Apache web server to all Microsoft browser users

RewriteCond %{REQUEST_URI} !^/fail/$
RewriteCond %{HTTP_USER_AGENT} .*MSIE.*
RewriteRule .* /fail/ [R]

This redirects to the /fail/ page on your web site.

It will be interesting to see what happens to my log files.
