[TYPO3-project-4-3] Testing the memcached backend

[Steffen Müller]

Hi.

I am about to test the caching framework and tried to use memcached for
cache_pages. Therefore I used the example configuration mentioned in
config_default.php.

Trying to login to the backend, my system throws exceptions:

<b>Fatal error</b>:  Uncaught exception 'ReflectionException' with
message 'Class  does not exist' in
/var/www/typo3_src/typo3_src-trunk/t3lib/class.t3lib_div.php:4701

  thrown in
<b>/var/www/typo3_src/typo3_src-trunk/t3lib/class.t3lib_div.php</b> on
line <b>4701</b><br />

I added these lines to localconf.php:

$TYPO3_CONF_VARS['SYS']['caching'] = array(
  'cacheConfigurations' => array(
    'cache_pages' => array(
      'backend' => 't3lib_cache_backend_MemcachedBackend',
      'options' => array(
        'servers' => array('localhost:11211'),
      ),
    ),
  ),
);

Also Frontend does not work.
using trunk rev5205, memcached 1.2.2 and php-memcache 3.0.1
Deleting typo3conf/temp_* did not help.
