I have a Ubuntu server running apache webserver and Tomcat; also Win7 client + IE11, FF, Chrome:

I understand that, as Ubuntu (Linux) differs upper from lowercase, it does make a diffence from default.jpg to default.JPG ..

Now in our Tomcat application thumbnails of *.JPG do not show up, but only in Internet Explorer (11).
Chrome and Firefox seem to not care very much - no problems.

So I guess I have to add the uppercase MIME types to the web.xml - but I would like to know, why/how IE handles MIME Types differently to other browsers?
Of couse, it is strongly entagled with Windows OS which itself also does not differ upper and lowercase.. So is the root cause of this, how the mime types are defined (in the registry?) and processed by different browsers (Chrome/FF handling MIME types on their own)?

Can somebody confirm this and/or give a more detailed reason?
