I have a very weird problem that can't wrap my head around here.
We have a folder with an XML language file for which we just received an updated files. So we have overwritten the old one.
Now When we open that XML file in IE it's content is displayed, however the content that is displayed is the older version of this file that was overwritten.
When I right click and choose 'View source' the newer correct version is shown.
If I rename the file, and open it in IE the correct version is also shown.
It does not happen with Chrome or Firefox.
The problem is that the language file is read by an application, which also reads the older version, so renaming it is not an option.
I have already deleted the cache, and did a disk cleanup removing all temporary files. The problem still persists.
