Zend-framework設定快取

$this->getResponse()->setHeader('Expires', '', true);
$this->getResponse()->setHeader('Cache-Control', 'public', true);
$this->getResponse()->setHeader('Cache-Control', 'max-age=3800');
$this->getResponse()->setHeader('Pragma', '', true);
透過重寫ZendFramework的Header可以設定快取

也可以輸出XML的Header
$this->getResponse()->setHeader('Content-Type', 'text/html; charset=UTF-8');
