I'm working on troubleshooting a feature that works for most users, but does not work for some. The users that have reported the issue seem to all have the following user agent string:
User agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0; MALC)
So looking at the string it's an IE9, on Windows 7, 32-bit version of Internet Explorer is running on a 64-bit processor, running as IE9 (Trident/5.0 and MSIE 9.0 match).
However, I have no idea what MALC means. Googling it didn't get me any leads. Please help.
