  • With WP Faster Cache running, the GTMetrix rating for browser caching on my site is a miserable 15 (F).

    The explanation reads “The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources:” (but it doesn’t tell me how to specify them) and 11 resources are listed with “expiration not specified” after them. These are css, js, jpg, png files.

    Is there a setting for WP Faster Cache to correct this, or is it done in the .htaccess file, or somewhere else in WordPress?

    GTMetrix on their browser cacheing explanation page has about a dozen lines for a .htaccess file to indicate expiration times for different types of files:

    ## EXPIRES CACHING ##
    <IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType image/jpg "access plus 1 year"
    ExpiresByType image/jpeg "access plus 1 year"
    ExpiresByType image/gif "access plus 1 year"
    ExpiresByType image/png "access plus 1 year"
    ExpiresByType text/css "access plus 1 month"
    ExpiresByType application/pdf "access plus 1 month"
    ExpiresByType text/x-javascript "access plus 1 month"
    ExpiresByType application/x-shockwave-flash "access plus 1 month"
    ExpiresByType image/x-icon "access plus 1 year"
    ExpiresDefault "access plus 2 days"
    </IfModule>

    However, WP Faster Cache already has directives in the .htaccess file:

    <FilesMatch "\.(html|htm|shtml)$">
    FileETag None
    <ifModule mod_headers.c>
    Header unset ETag
    Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
    Header set Pragma "no-cache"
    Header set Expires "Mon, 29 Oct 1923 20:30:00 GMT"
    </ifModule>
    </FilesMatch>

    I have no idea what these mean or why they seem limited to html,htm,shtml files. Can someone give me a recommendation on how to improve this function?

    Thanks,
    Peter
    My hosting company definitely has mod_headers.c running on the server.
