proxy.pac autoconfiguration scripts have been working since IE6 up thought IE8. With IE9 portions of the script now are failing or ignored. It appears that the "DIRECT" keyword is now required to be capitalized. Our previous scripts had it as "Direct" and things worked just fine.
Can you point me to any documentation that talks specifically about changes like this to javascript in IE9? I looked at the "Features Changed in IE9" document didn't see any specifics.
