# [Plugin: WP Super Cache] – adding max-age for images/css

 * Hi,
 * I use the mod-rewrite option in WP Super Cache, it seems to work.
 * As the plugin does not add expiry dates or max-age for images or css, I modified
   the .htaccess file in the cache folder (wp-content/cache/) manually and added
   max-ages for images and css. (I cannot use the expiry module with my virtual 
   server, so I cannot add expiry dates.)
 * I added the following code to the .htaccess file in the cache folder:
 *     ```
       # BEGIN Cache-Control Headers
       <ifmodule mod_headers.c>
         <filesmatch "\.(flv|gif|jpg|jpeg|png|ico|swf)$">
               Header set Cache-Control "max-age=86400"
         </filesmatch>
         <filesmatch "\.(css|pdf)$">
               Header set Cache-Control "max-age=86400"
         </filesmatch>
         <filesmatch "\.(js)$">
               Header set Cache-Control "max-age=86400, private"
         </filesmatch>
       </ifmodule>
       ```
   
 * The whole file now looks like this:
    [http://pastebin.com/B4WGnTjM](http://pastebin.com/B4WGnTjM)
 * But when I check the browser caching of static assets, I still get the message:
   No max-age or expires for the images and the css file.
 * Can anyone please help?
    Many thanks in advance.

 * Add that code to your main .htaccess file as images and css aren’t cached!

 * I just want to confirm that it’s not possible to set caching time limits for 
   CSS and JS, especially when you’re using a CDN.
 * But, now that I’ve seen this, I guess we can write the rules to .htaccess.
 * What is the recommended time to set CSS or JS. I see you have here 1 day or 86400
   seconds. Any recommendation on how long to set it to if you’re using a CDN.

 * This is resolved. I got the answer on the IRC channel from Donncha.
 * Settings are what you’re comfortable with.
 * We’re going with 172800 (2 days) for CSS and JS and images at 600 seconds (10
   min) because we’re a news org that updates stories with images frequently.
