I'm having an issue with page cache (disk enhanced) and pages updating in Internet Explorer. All my IE users had this problem. If I turn on page cache disk enhanced they get served this weeks old version of the site (the same one every time). I tried emptying all the caches, etc. but nothign works. No issues on firefox or chrome. If I change it to page cache disk (not enhanced) things appear to work fine, though using debug mode it doesn't seem to cache anything.
Help would be much appreciated, thanks!
