How to add a prefix to all my routes in Play Framework 2?

In play 1.x you had the http.path param which allowed you to set a url to add to every route

http.param

How can I achieve someting similar in play 2.0?

In Play 2.1 you can do that with the following option in conf/application.conf:

application.context="/your/prefix"

From Play 2.4 this property is called play.http.context (taken from the comment by Gman).

I asked at play's discussion group and they helped me achieve this initial version

I create a PrefixedRequest like this

import play.api.mvc.RequestHeader
import play.api.Play.configuration

import play.api.Play.current

class PrefixedRequest(request: RequestHeader) extends RequestHeader {

    def headers = request.headers
    def queryString = request.queryString

    // strip first part of path and uri if it matches http.path config
    def path = ("^" + prefix).r.replaceFirstIn(request.path, "/")
    def uri = ("^" + prefix).r.replaceFirstIn(request.uri, "/")

    def method = request.method
    def remoteAddress = request.remoteAddress

    lazy val prefix = {
      val config = configuration.getString("http.path").getOrElse("")
      if (config.endsWith("/")) config else config + "/"
  }
}

object PrefixedRequest {
  def apply(request: RequestHeader) = new PrefixedRequest(request)
}

Then I used it in Global.scala

import play.api.GlobalSettings
import play.api.mvc.RequestHeader
import play.api.mvc.Handler

object Global extends GlobalSettings {

  override def onRouteRequest(request: RequestHeader): Option[Handler] = {
    super.onRouteRequest(PrefixedRequest(request))
  }

}

finnally added this to application.conf

http.path=/prefix/

It seems to work, but I couln't find out how to add that prefix to the reversed routes... can anybody gimme a hand on that part?
