Using the code above, I was getting a false positive for ie6 on ie7 until I added a && window.XMLHttpRequest == null to the check for ie6.

IE3 support? what?! are you serious?

Most web apps today won’t support less than IE6, and even then, only grudgingly.

Great articel!

I use another way to identify IE 7 by checking the window.XMLHttpRequest - just in case anybody is interested:
BO[”ie7″] = (BO[”ie”] && document.implementation != null && document.compatMode != null && window.XMLHttpRequest != null)

Just added IE7 support, since that was lacking.

That work by checking the JScript engine version, since that was updated for IE7.

I am not sure if this will work on machines with multiple Ie versions installed. If someone can check that it would be nice.

Very nice, only thing one could comment about is the lag of IE3 support. But as many of our readers would agree there is close to no users using IE3 anymore.
