 * Hi,
    I have compression active in the plugin under Browser caching. And yet it’s
   not working since I get related messages from tests:
 * Google PageSpeed Insights:
    “Activate compression” “Reduce JavaScript”
 * tools.pingdom.com:
    “Specify a Vary: Accept-Encoding header”
 * Including the relevant HTACCES part below. What can I check/do?
 * Thanks!
 *     ```

 * One addition: the problem could be related to minify of course. I have that active
   as well. The pingdom analysis shows though, that files aren’t loaded from the
   minify cache, instead the original ones are loaded. how is this possible?
 * Minify HTACCESS below.
    Thanks!
