Issue Serving files in Sub-Routes.

[xnpltn]

Trying to serve files using this piece of code .

func main(){

	router:= mux.NewRouter()
	// :8080/h/css/test.css
	router.PathPrefix("/hx/").Handler(http.StripPrefix("/hx", http.FileServer(http.Dir("uploads/"))))
	v1Router := router.PathPrefix("/v1").Subrouter()

	// NOT WORKING
	v1Router.PathPrefix("/hx/").Handler(http.StripPrefix("/hx", http.FileServer(http.Dir("uploads/"))))
	http.ListenAndServe("localhost:8080", router)	
}

It is working for the main router ( router ) but not for the sub-router (v1Router).
Any Idea how to solve the issue?
