Where is the isAjax() method in Play Framework 2.0?

Question

In Play Framework 1.x, we could quickly know if the request was AJAX or not by asking request.isAjax() method, but I can't find it on Play 2.

What is the alternative or where is this method?

Answer 1

If you use JQuery for Ajax, it sets the following Request Header:

 X-Requested-With: XMLHttpRequest

that you can later access to test if a call is done via Ajax or not.

Answer 2

You can define it as a method and use it in your controller:

def isAjax[A](implicit request : Request[A]) = {
  request.headers.get("X-Requested-With") == Some("XMLHttpRequest")
}
