Hi.
I noticed that on my private instance testing machines static assets with properly set expiration headers are not cached by Internet Explorer. What is interesting this happens only when tested with webpagetest. When checked manually with fiddler, the browser caches everything properly.
What is possible reason for that? "Check for newer versions of stored pages" is set to "automatically" - default setting. I have no idea what else can interfere with caching. The only correlation I noticed is that caching problem applies to IE11. On machines running IE9 I cannot notice anything like that.
