Provides utilities to mark controller actions as deferred. By simply
adding the @Defer annotation to any Controller or Action, the request
will be intercepted during the KernelEvents::CONTROLLER phase of the
HttpKernel. At this point in time, the Request object will be serialized
and stored in the database for later processing via the deferred-request:process
console command.
When a Request is deferred, an appropriate HTTP 202 Response is returned containing :
- A Content-Location Header indicating where the deferred Response will be found
- A Link Header indicating where the status of the deferred Request may be monitored
