I mention that I'm running a WP site only if that matters. The OS is CentOS 7 and I host the server.
When I test my site with https://tools.pingdom.com , it scores me an 89 in the area of Expires Headers. I'm hoping someone can tell me what else I might want to add, so I have a "complete" list of Expires Headers? Here's what I have in my httpd.conf file: <IfModule mod_expires.c> # Enable cache expirations ExpiresActive On # Default directive ExpiresDefault "access plus 1 month" # My favicon ExpiresByType image/x-icon "access plus 1 year" # 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" # Webfonts ExpiresByType font/truetype "access plus 1 year" ExpiresByType font/opentype "access plus 1 year" ExpiresByType application/x-font-woff "access plus 1 year" ExpiresByType image/svg+xml "access plus 1 year" ExpiresByType application/vnd.ms-fontobject "access plus 1 year" # CSS and JavaScript ExpiresByType text/css "access plus 1 year" ExpiresByType application/javascript "access plus 1 year" ExpiresByType text/javascript "access plus 1 year" ExpiresByType text/x-javascript "access plus 1 month" # Misc. files ExpiresByType application/pdf "access plus 1 month" ExpiresByType application/x-shockwave-flash "access plus 1 month" ExpiresDefault "access plus 2 days" </IfModule> <IfModule mod_headers.c> Header append Cache-Control "public" </IfModule> Thank you, Ed
