       $result = wp_cache_get( 'my_cache' );
       	if ( false == $result ) {
       		$result = 'cache doesnt work';
       		wp_cache_set( 'my_cache', $result );
       		echo 'cache: false <br>';
       	} else $result = 'cache works perfectly';

 * Was having problems in wordpress 3.0.4 with the code above (and other object 
   caching tests)
 * I had problems with W3 Total Cache Version 0.9.1.3.
 * Tried [WP File Cache](http://wordpress.org/extend/plugins/wp-file-cache/) plugin
   and got the cache working.
 * Now invistigating why W3 Total Cache is not working.
 * Note: I am using a multisite setup with one other plugin enabled WordPress MU
   Domain Mapping.
 * If any one has the solution or know what’s causing the problem help is welcome.

 * Ok figured it out… the problem was that W3 Total Cache wasn’t loading the right
   config file (since I was remapping my domain)
 * I have a multisite setup which is basically as follows
 * 1. main domaain my-blogs.com
    2. multisite enabled with subdomain with site blog1.
   my-blogs.com 3. using WordPress MU Domain Mapping so that blog1.my-blogs.com 
   redirectos to my-real-blog.com
 * Problem was that W3 Total Cache was trying to load the config file w3-total-cache-
   config-my-real-blog.com.php instead of w3-total-cache-config-blog1.my-blogs.com.
   php.
 * What I did to fix the problem I created a symlink from w3-total-cache-config-
   blog1.my-blogs.com.php to w3-total-cache-config-my-real-blog.com.php.
