                Cake\Http\ServerRequest$request
- The request object to use. 
- 
                Cake\Http\Response$response
- The response object to use.

_getAssetFile() ¶ protected
_getAssetFile(string $url): stringBuilds asset file path based off url
Parameters
- 
                string$url
- Asset URL 
Returns
stringAbsolute path for asset file
afterDispatch() ¶ public
afterDispatch(Cake\Event\Event $event): voidMethod called after the controller served a request and generated a response. It is possible to alter the response object at this point as it is not sent to the client yet.
If false is returned, the event will be stopped and no more listeners will be notified.
Alternatively you can call $event->stopPropagation() to achieve the same result.
Parameters
- 
                Cake\Event\Event$event
- container object having the - requestand- responsekeys in the data property.
Returns
voidbeforeDispatch() ¶ public
beforeDispatch(Cake\Event\Event $event): Cake\Http\Response|nullChecks if a requested asset exists and sends it to the browser
If a Cake\Http\Response object instance is returned, it will be served at the end of the event cycle, not calling any controller as a result. This will also have the effect of not calling the after event in the dispatcher.
If false is returned, the event will be stopped and no more listeners will be notified.
Alternatively you can call $event->stopPropagation() to achieve the same result.
Parameters
- 
                Cake\Event\Event$event
- Event containing the request and response object 
Returns
Cake\Http\Response|nullIf the client is requesting a recognized asset, null otherwise
Throws
Cake\Network\Exception\NotFoundExceptionWhen asset not found

$this->getConfig('key');Reading a nested value:
$this->getConfig('some.nested.key');Parameters
- 
                string|null$key optional

handle() ¶ public
handle(Cake\Event\Event $event): mixedHandler method that applies conditions and resolves the correct method to call.

- The event instance. 
Returns
mixedimplementedEvents() ¶ public
implementedEvents(): arrayReturns the list of events this filter listens to.
