How to use Cache::remember with HttpSocket->post cakephp

Question

I want to cache HttpSocket->post calling in CakePHP 2.

I'm calling the following code:

$content = Cache::remember($key, function () use ($rateUrl, $xml, $uid) {
    App::uses('HttpSocket', 'Network/Http');
    $HttpSocket = new HttpSocket(array('ssl_verify_peer' => false));
    return $HttpSocket->post($rateUrl, $xml->asXML(), array(
        'header' => array(
            'Content-Type' => 'text/xml',
            'RestUid' => $uid,
        )
    ));
});

But I'm getting this error:

The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "HttpSocketResponse" of the object you are trying to operate on was loaded before unserialize() gets called or provide a __autoload() function to load the class definition

Do anybody know the way how to use the HttpSocket class in an anonymous function or call in CakePHP or otherwise?

As the error message says, you have to

[...] ensure that the class definition "HttpSocketResponse" of the object you are trying to operate on was loaded before unserialize() gets called or provide a __autoload() function to load the class definition

The class definition for the serilaized object of type HttpSocketResponse isn't available when it has been deserialized, so things won't work. Either add a corresponding App::uses statement before invoking Cache::remember(), so that CakePHPs autoloader can load the required class definition

App::uses('HttpSocketResponse', 'Network/Http');

$content = Cache::remember(/* ... */);

or switch to using Composer, so that the required class can be autoloaded without any App::uses() calls. Alternatively it's also possible to use the unserialize_callback_func ini directive to define a callback that loads the required class definition.
