§Intercepting requests

§Overriding onRouteRequest

One another important aspect of the Global object is that it provides a way to intercept requests and execute business logic before a request is dispatched to an Action.

Tip This hook can be also used for hijacking requests, allowing developers to plug-in their own request routing mechanism.

Let’s see how this works in practice:

import play.api._

// Note: this is in the default package.
object Global extends GlobalSettings {

  def onRouteRequest(request: RequestHeader): Option[Handler] = {
     println("executed before every request:" + request.toString)
     super.onRouteRequest(request)
  }

}

It’s also possible to intercept a specific Action method, using Action composition .
