Htaccess to use browser caching not working

I'm having problems caching Leverage browsers. I created this .htaccess file and use it on my server, but it does not seem to work, I copied it here. http://www.samaxes.com/2011/05/improving-web-performance-with-apache-and-htaccess/ ". I most likely make a basic mistake, so any help would be nice. here are some details. I I’m working on a subdomain, I’ll call it “sub” and “domain" of the main domain. so I want everything in http://sub.example.com/ for the htaccess file to work. on my server I put the .htaccess file in the main directory , which, for example, is divided into the main one.

I am running apache2 server with support for mod_headers and mod_expires.

Greetings.

looks very dirty.

You also have redundant rules like

ExpiresByType application/javascript "access plus 216000 seconds"

and

<filesMatch "\\.(js|js.gz)$">
Header set Cache-Control "max-age=604800, private"
</filesMatch>

Try using cleanup rules (and update) from html5-boilerplate or check all h5bp server configurations

use this option and try:

    <ifModule mod_expires.c>
 ExpiresActive On
 ExpiresDefault "access plus 5 seconds"
 ExpiresByType image/x-icon "access plus 2592000 seconds"
 ExpiresByType image/jpeg "access plus 2592000 seconds"
 ExpiresByType image/png "access plus 2592000 seconds"
 ExpiresByType image/gif "access plus 2592000 seconds"
 ExpiresByType application/x-shockwave-flash "access plus 2592000 seconds"
 ExpiresByType text/css "access plus 604800 seconds"
 ExpiresByType text/javascript "access plus 216000 seconds"
 ExpiresByType application/javascript "access plus 216000 seconds"
 ExpiresByType application/x-javascript "access plus 216000 seconds"
 ExpiresByType text/html "access plus 600 seconds"
 ExpiresByType application/xhtml+xml "access plus 600 seconds"
 </ifModule>

As @Anthony Hatzopoulos noted, you use duplicate configurations and they can be inconsistent. Of course, if you like it, you can also use "fileMatch", but the fact is that this is not good code. Please note that if you use "fileMatch", you are not using this code.
