package controllers 
import "github.com/astaxie/beego"
type SessionController struct 
{
  beego.Controller
}
func (this *SessionController) Home() 
{
  isAuthenticated := this.GetSession("authenticated")
  if isAuthenticated == nil || isAuthenticated == false 
  {
    this.Ctx.WriteString("You are unauthorized to
