I have some pages that require a case sensitive input in the URL.  Like /page/MT with 'MT' being the param.  I've noticed lots of error reports lately where 'MT' is converted to 'mt', which is unexpected and currently unsupported.All of these requests seem to be from a version of IE9 that reports its user-agent as 'Mozilla/5.0 (Windows; U; MSIE 9.0; Windows NT 9.0; en-US)'.  Lots of different IPs, so it's not unique to just one user.My first guess was maybe just bad external links, which seems to happen a lot.  However, all the requests show internal pages as the referrer.I tried testing with the IE9(9.0.8112.16521) I had available with no luck.  It behaved as I would expect.  This is a proxied wsgi webapp, but the only common thread between all the problems is IE9.Has anyone else seen this before?
Is some version of IE9 lowercasing URLs?
url;internet explorer 9
That UA string suggests it isn't Internet Explorer at all, supporting ionFish's theory that it's a bot.Windows NT 9.0 gives it away. Even Windows 8 only calls itself Windows NT 6.2. It also makes no reference to Trident, IE's rendering engine.It should be more like Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0).
