I have a question about .htaccess and server caching in Internet Explorer. Internet explorer won't cache my css and js files, e.g. this is the reading from the Network monitor in IE11 for style.css:
It does a similar thing for print.css, jquery.min.js and functions.js.
<IfModule mod_deflate.c>

BrowserMatch ^Mozilla/4\.[0678] no-gzip
# MSIE masquerades as Netscape, but it is fine
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
# NOTE: Due to a bug in mod_setenvif up to Apache 2.0.48, the above regex won’t work. You can use the following
# workaround (comment the above line and uncomment the below line) to get the desired effect:
# BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html
# Make sure proxies don’t deliver the wrong content
Header append Vary User-Agent env=!dont-vary
