See [http://framework.zend.com/issues/browse/ZF-4226]

There is a error when check the domain of a cookie, I finally found that exists an error in the comparision way.

Valid domain are:

.zend.com => must catch zend.com and anything.zend.com .www.zend.com => must catch www.zend.com and anything.www.zend.com, this's not works right now.

Invalid domain are:

.com.ar .or com. or .com => the script doesn't check this. zend.com without initial dot.

This is the code that fails:

    protected function _matchDomain($domain) {
        $ret = array();

        foreach (array_keys($this->cookies) as $cdom) {
                      $regex = "/" . preg_quote($cdom, "/") . "$/i";
              if (preg_match($regex, $domain)) $ret[$cdom] = &$this->cookies[$cdom];
        }
        return $ret;
    }

Here a faster but not ideal, solution:

    protected function _matchDomain($domain) {
        $ret = array();

        foreach (array_keys($this->cookies) as $cdom) {
                      $regex = '/\.' . preg_quote($domain, '/') . '$/i';
              if (preg_match($regex, $cdom)) $ret[$cdom] = &$this->cookies[$cdom];
        }
        return $ret;
    }

This only fix the valid domain issue.

Regards.
