Thanks for your quick response. I have placed var_dump($driver) after  
all of the if statements within that particular methond.

Here is what factory() looks like in my install:

     function factory($driver, $params = array())
     {

         var_dump($driver);

         if (is_array($driver)) {
             $app = $driver[0];
             $driver = $driver[1];
         }

         var_dump($driver);

         $driver = basename($driver);
         if (empty($driver) || $driver == 'none') {
             return new Horde_Cache($params);
         }

         var_dump($driver);

         if (!empty($app)) {
             include_once $app . '/lib/Cache/' . $driver . '.php';
         } elseif (file_exists(dirname(__FILE__) . '/Cache/' . $driver  
. '.php')) {
             include_once dirname(__FILE__) . '/Cache/' . $driver . '.php';

         } else {
             include_once 'Horde/Cache/' . $driver . '.php';
         }

         var_dump($driver);

         $class = 'Horde_Cache_' . $driver;
         if (class_exists($class)) {
             $cache = new $class($params);
         } else {
             $cache = PEAR::raiseError('Class definition of ' . $class  
. ' not found
.');
         }

         return $cache;
     }
