Hi, I am using Zend Cache with page caching but it seems to miss the cache after a period of time. For a while it is OK, but I come back tomorrow and hit the page, it doesn't fetch the contents from the cache. why?
$frontendOptions = array(
'content_type_memorization' => true, // This remembers the headers, needed for images
'lifetime' => NULL, // cache lifetime forever
'automatic_serialization' => true,
'automatic_cleaning_factor' => 0
);
$myPageCache = new Zend_Cache_Frontend_Page(array(
'debug_header' => false,
'automatic_cleaning_factor'=>0,
'content_type_memorization' => true,
'default_options' => array(
'cache' => true,
'cache_with_get_variables' => true,
'cache_with_post_variables' => true,
'cache_with_session_variables' => true,
'cache_with_cookie_variables' => true
)));
$backendOptions = array('cache_dir' => '.' . DIRECTORY_SEPARATOR . 'cache' . DIRECTORY_SEPARATOR);
$cache = Zend_Cache::factory($myPageCache,
'File',
$frontendOptions,
$backendOptions);
$cacheKey = hash('md5', "cache_" . $cachePath); // cachePath is the key I use for the cache
if(!$cache->start($cacheKey)) {
I output html here
$cache->end();
}
