ZF-5854: Doesn't work with domains without two dots, such as dev.local
Zend_Http_Cookie doesn't work with local domains without two dots, such as dev.local. With the native php cookie method one can use false instead of the domain, e.g. setcookie('key', 'val', time() + 7200, '/', false); to make it work.
This doesn't work with the Zend component. See this thread for a more elaborate discussion on the problem.
