was starting to write you should have a look at the doc
http://symfony.com/doc/2.0/book

but actually, it is not in there, or at least not where i would expect
it to be.

however, google for symfony2 event brings up this as second result:
http://blog.bearwoods.dk/symfony2-adding-a-event-listener

there is also a way to specify what event you want to listen to, for example

services:
    liip.demo.cachecontrol:
        class: Liip\CoreBundle\Helper\CacheControl
        tags:
            - { name: kernel.listener, event: onCoreResponse }
