Ik ben een website aan het optimaliseren voor SEO.
GTmetrix geeft de volgende medling:
The following resources are missing a cache validator. Resources that do not specify a cache validator cannot be refreshed efficiently. Specify a Last-Modified or ETag header to enable cache validation for the following resources:
www.deijsmannetjes.nl/media/template/gzi...ate.min-84df0ffb.css
www.deijsmannetjes.nl/media/template/gzi...otstrap-141f5cd3.css
www.deijsmannetjes.nl/media/template/gzi...trap.min-f61e86c3.js
www.deijsmannetjes.nl/media/template/gzi...ome.min-3f8b82e6.css
www.deijsmannetjes.nl/media/template/gzi...rate.min-bb3e61c1.js
www.deijsmannetjes.nl/media/template/gzi...conflict-d9c0b6b7.js
Ik lees in fora dat je dit op kunt losse door allerlei cache expiratietijden in .htaccess aan te passen.
Nu staat er in mij .htaccess al het volgende:
Code:
## BEGIN EXPIRES CACHING - JCH OPTIMIZE ##
<IfModule mod_expires.c>
ExpiresActive on
# Perhaps better to whitelist expires rules? Perhaps.
ExpiresDefault "access plus 1 month"
# cache.appcache needs re-requests in FF 3.6 (thanks Remy ~Introducing HTML5)
ExpiresByType text/cache-manifest "access plus 0 seconds"
# Your document html
ExpiresByType text/html "access plus 0 seconds"
# Data
ExpiresByType text/xml "access plus 0 seconds"
ExpiresByType application/xml "access plus 0 seconds"
ExpiresByType application/json "access plus 0 seconds"
# Feed
ExpiresByType application/rss+xml "access plus 1 hour"
ExpiresByType application/atom+xml "access plus 1 hour"
# Favicon (cannot be renamed)
ExpiresByType image/x-icon "access plus 1 week"
# Media: images, video, audio
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"
ExpiresByType video/ogg "access plus 1 month"
ExpiresByType audio/ogg "access plus 1 month"
ExpiresByType video/mp4 "access plus 1 month"
ExpiresByType video/webm "access plus 1 month"
# HTC files (css3pie)
ExpiresByType text/x-component "access plus 1 month"
# Webfonts
ExpiresByType application/font-ttf "access plus 1 month"
ExpiresByType font/opentype "access plus 1 month"
ExpiresByType application/font-woff "access plus 1 month"
ExpiresByType application/font-woff2 "access plus 1 month"
ExpiresByType image/svg+xml "access plus 1 month"
ExpiresByType application/vnd.ms-fontobject "access plus 1 month"
# CSS and JavaScript
ExpiresByType text/css "access plus 1 year"
ExpiresByType text/javascript "access plus 1 year"
ExpiresByType application/javascript "access plus 1 year"
<IfModule mod_headers.c>
Header append Cache-Control "public"
</IfModule>
</IfModule>
Ik ben geen .htaccess expert, maar ik krijg toch de indruk dat overal de cache expiraties op minimaal 1 maand staan.
Weet iemand of ik nog iets aan moet passen om de medling van GTetrix op te lossen?
