Add request parameter to request

Question

I need to put a flag in an kernel.event_listener at stage kernel.controller in order to do something in an kernel.response-listener.

I thought about adding a parameter to the $request object, however have not found any method or this:

http://api.symfony.com/2.0/Symfony/Component/HttpFoundation/Request.html

What is the best practice to pass some informatino from an kernel.controller-listener to an kernel.response-listener?

Use-case:

• We want to set a cookie based on a validation of a specific request attribute (must be in kernel.controller-stage, since based on the result of the validation, the view may behave different).
• The cookie can only be set in the kernel.response-listener, since it has the Response-instance.

You can use $request->attributes to pass around information. In your controller listener:

$request->attributes->set('mykey', 'myvalue'); 

In your response listener:

$myvalue = $request->attributes->get('mykey');
