 * I ran into the weird problem that every request for a page did NOT work on the
   first attempt, but DID work on the second attempt, as shown in this terminal 
   session (domain name changed to example.com);
 * %telnet [http://www.example.com](http://www.example.com) 80

   is ‘^]’. GET [http://www.example.com/index.php](http://www.example.com/index.php)

 * When I comment the line define(‘WP_CACHE’, true); in wp-config.php, the problem
   diseappears.
 * Anybody else seen this?

 * Found it. In wp-content/plugins/wp-cache/wp-cache-phase2.php, change in the function
   wp_cache_ob_end, the call to ob_end_clean() to ob_end_flush().
