how to pass parameters in url without showing in url in playframework

In my Controller i have two Actions ActionA and ActionB ,In ActionA i have a string which i want to send to ActionB for that i am doing it like this

 object MyController extends Controller {

    def ActionA= Action {
       var str="abc"
          Redirect(controllers.routes.MyController.ActionB(str))
      }

    def signupProcessing1(token:String)= Action {
        Ok("string is " + token)   
      } 
    }

in the route file 

GET    /user/actionB controllers.MyController.ActionB(token:String)  

GET   /user/actionA  controllers.MyUserController.ActionA

when i hit localhost:9000/user/actionA in browser its redirected to this url 

localhost:9000/user/actionB?token="abc"

i do not want to show this string "abc" in the url for that i used POST instead of GET 

POST    /user/actionB controllers.MyController.ActionB(token:String)  

GET   /user/actionA  controllers.MyController.ActionA

But it gives Exception

`Action not found` 

    For request 'GET /user/actionB?token=abc'

Please help me how can i pass parameters from one Action to another without showing in the url

The HTTP specification for redirect is not meant to change the method from GET to POST.

But there are a few things you can do to solve your problem.

The simplest approach is to not Redirect, just forward to your action:

  def ActionA = {
    val str = "abc"
    ActionB(str)
  }

  def ActionB(token: String) = Action {
    Ok("string is " + token)
  }

In this case the URL will remain ActionA

Another approach is to use a cookie

  def ActionA = Action {
    val str="abc"
    Redirect(controllers.routes.MyController.ActionB).withCookies(
      Cookie("token", str))
  }

  def ActionB = Action { r =>
    r.cookies.get("token") match {
      case Some(cookie) =>
        val token = cookie.value
        Ok("string is " + token)
      case _ => Unauthorized
    }
  }

In this case the url will change to ActionB

If you are interested in Authentication and Authorization implementations you can take a look at some of them here
