[TYPO3-english] CF my backend

[Tomasz Krawczyk]

Hi list!

I'm writing an extension which adds my own caching backend. Backend uses 
WinCache. Best opcode cacher for IIS.

I added it in ext_autoload.php
<?php
$extensionPath = t3lib_extMgm::extPath('wincache');

return array(
     'tx_wincache_cache_backend_WinCacheBackend' => $extensionPath . 
'classes/class.tx_wincache_cache_backend_wincachebackend.php',
);

?>

and ext_localconf.php.
<?php
if (!defined ('TYPO3_MODE')) {
     die ('Access denied.');
}

$extensionPath = t3lib_extMgm::extPath('wincache');

$TYPO3_CONF_VARS['SYS']['caching']['cacheBackends']['tx_wincache_cache_backend_WinCacheBackend']
	= 
'typo3conf/ext/wincache/classes/class.tx_wincache_cache_backend_wincachebackend.php:tx_wincache_cache_backend_WinCacheBackend';

?>

In my localconf.php I added useCachingFramework = 1 and pointed CF to 
use my backend. It looked all works with debugging options turned on but 
when I disabled debugging options I got such errors.
