    public function contains(RequestInterface $request) {
        $ret = $this->storageCache->hasItem($this->buildKey($request));
        return $ret;

    public function cache(RequestInterface $request, ResponseInterface $response) {
        return $this->storageCache->setItem($this->buildKey($request), $response);
    }

    public function delete(RequestInterface $request) {
        return $this->storageCache->removeItem($this->buildKey($request));
    }

    public function fetch(RequestInterface $request) {

	if (!$message) {
	    return null;
	}
	
	$factory = new MessageFactory();
	$response = $factory->fromMessage($message);

The expression $factory->fromMessage($message); of type GuzzleHttp\Message\ResponseInterface|GuzzleHttp\Message\RequestInterface adds the type GuzzleHttp\Message\RequestInterface to the return on line 54 which is incompatible with the return type declared by the interface GuzzleHttp\Subscriber\Cache\CacheStorageInterface::fetch of type null|GuzzleHttp\Message\ResponseInterface.

	
	if ($response->getStatusCode() != 200) {

The method getStatusCode does only exist in GuzzleHttp\Message\ResponseInterface, but not in GuzzleHttp\Message\RequestInterface.

	    return null;
	}
	        
	return $response;
    }

    public function purge($url) {
	// @@TODO REVISAR ESTE METODO
        return $this->storageCache->removeItem($this->buildKey($url));

$url is of type string, but the function expects a object<GuzzleHttp\Message\RequestInterface>.

    }

    private function buildKey(RequestInterface $request) {        
        return md5($request->getUrl());
    }

It is not recommended to use PHP's closing tag ?> in files other than templates.
