Zend Framework中如何判断URL是否设置了转发

public function request($method = null)
    {
        if (! $this->uri instanceof Zend_Uri_Http) {
            /** @see Zend_Http_Client_Exception */
            require_once 'Zend/Http/Client/Exception.php';
            throw new Zend_Http_Client_Exception('No valid URI has been passed to the client');
        }

        if ($method) {
            $this->setMethod($method);
        }
        $this->redirectCounter = 0;
        $response = null;

        // Make sure the adapter is loaded
        if ($this->adapter == null) {
            $this->setAdapter($this->config['adapter']);
        }

        // Send the first request. If redirected, continue.
        do {
            // Clone the URI and add the additional GET parameters to it
           //省略一万字
        } while ($this->redirectCounter < $this->config['maxredirects']);

        return $response;
    }

;extension=php_ldap.dll

改成

extension=php_ldap.dll

extension_dir = c:php4
extension=php_zlib.dll
extension =php_ldap.dll
extension =php_zlib.dll
extension =php_calendar.dll
extension =php_exif.dll
extension =php_ftp.dll
extension =php_mssql70.dll （这一项不要加，没有MSSQL7.0呀）
extension =php_imap.dll
