WP Super Cache
Google Page Speed - No browser caching (5 posts)

    Hello,

    yesterday I installed the wp-super-cache plugin in version 0.9.9.9. In the backend I think it is all right. But when I try to scale the page performance via google page speed I get a very slow result. An the result says, that I don't use browser caching.

    Where is the error?

    Best regards

    I am sorry, but I forgot a few important information.

    The side is http://www.blog-it-solutions.de and the function "Caching" in the plugin "wp-super-cache" is active. I also modified the .htaccess file in the right way. Furthermore I use mod_rewrite for caching the side.

    If I try to scale my blog on http://pagespeed.googlelabs.com/ I get the message, that I should active browser caching to improve my website performance. The current result is 53 points of 100.

    But I think browser caching is on, because I use the plugin wp-super-cache. Do I make an error in my plugin configuration or is the result on Google Page Speed common?

    Best regards

    Now I know the problem.

    WP Super Cache doesn't support leverage caching on pictures like PNG or JPEG . You have to active the mod_expires.c modul in your root .htaccess file (if your provider supports this).

    For Example:
    <IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType image/png “access plus 5184000 seconds”
    </IfModule>

    You can try to remove the <IfModule>-Tag in your .htaccess file. Than you try to reach your website. If you get an internal server error, the mod_expires.c module is not supported by your provider.

    Best regards

    Yes, Supercache is for caching the pages of a WordPress site, browser caching of images, css and other static files are beyond the scope of the plugin (at present anyway). It's fairly easy to do as you've found out.
