class WebDebugToolbarListener implements EventSubscriberInterface

WebDebugToolbarListener injects the Web Debug Toolbar.

The onKernelResponse method must be connected to the kernel.response event.

The WDT is only injected on well-formed HTML (with a proper tag). This means that the WDT is never included in sub-requests or ESI requests.
