GTMetrix Shows files that still need to "Leverage Browser Caching"

Facing the same issue, please someone from developers could throw some light on the cause??

You can always add the code manually to your .htaccess file (save a backup copy first):

# BEGIN Expire headers
<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 648000 seconds"
    ExpiresByType application/javascript "access plus 648000 seconds"
    ExpiresByType application/x-javascript "access plus 648000 seconds"
    ExpiresByType text/html "access plus 600 seconds"
    ExpiresByType application/xhtml+xml "access plus 600 seconds"
</ifModule>
# END Expire headers

Hi whyknott

Browser Caching with IIS 7 Windows server you should try by adding below script to your web.config file.

<?xml version=”1.0″ encoding=”UTF-8″?>
<configuration>
<system.webServer>
<staticContent>
<clientCache cacheControlMode=”UseMaxAge” cacheControlMaxAge=”10.00:00:00″ />
</staticContent>
</system.webServer>
</configuration>

@barnez your script in .htaccess ok for linux server
