Resolving YSlow’s “Add Expires headers” Low Grade
I found a good website speed tip that would help make those frequently requested files cacheable.
Using .htaccess you can add the following code add expire headers to your files:[php]<FilesMatch “\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$”>
Header set Expires “Thu, 15 Apr 2011 20:00:00 GMT”
NOTE: Backup your .htaccess file first before modifying it.
Now your site will load up a little bit faster.
