Zend_Cache_Frontend_Page bug

[PavelPolyakov]

Trying to have the cache for the page despite of cookies, get, post and other variables.
Like this:

$frontendOptions = array(
'lifetime' => 3600,
'debug_header' => false, // for debugging
'default_options' => array(
'cache' => false,
'cache_with_files_variables' => false,
'cache_with_get_variables' => false,
'cache_with_post_variables' => false,
'cache_with_cookie_variables' => false
),
'regexps' => array(
'^/$' => array('cache' => true),
'^/about$' => array('cache' => true),
'^/faq$' => array('cache' => true),
'^/price$' => array('cache' => true),
)
);

Would fail when you have cookies, because of the
protected function _makePartialId($arrayName, $bool1, $bool2) function.

And this part:

   if (count($var) > 0) {
       return false;
   }

The _makePartialId function would return false, the cache key would not be generated, the cache would not be stored.

The possible solution is using the next configuration values in the $frontendOptions:

           'cache_with_cookie_variables' => true,
           'make_id_with_cookie_variables' => false

So it would escape the function before that check.

I don't know the real purpose of the check, so I can't simply remove it and commit.
