# The SendResponseEvent

The MVC layer of Zend Framework 2 also incorporates and utilizes a custom `Zend\EventManager\Event`
implementation located at `Zend\Mvc\ResponseSender\SendResponseEvent`. This event allows listeners
to update the response object, by setting headers and content.

The methods it defines are:

- `setResponse($response)`
- `getResponse()`
- `setContentSent()`
- `contentSent()`
- `setHeadersSent()`
- `headersSent()`

## Listeners

Currently, three listeners are listening to this event at different priorities based on which
listener is used most.

Because all these listeners have negative priorities, adding your own logic to modify `Response`
object is easy: just add a new listener without any priority (it will default to 1) and it will
always be executed first.

## Triggerers

This event is executed when MvcEvent::FINISH event is triggered, with a priority of -10000.
