Buffalo Auth Tutorial: secure routes

app.go

// Create the secure group
secure := app.Group("/secure")
// Add the middleware CheckAuth to the group
secure.Use(CheckAuth)
// Create a simple secure handler, which renders a html file
secure.GET("/",
    func(c buffalo.Context) error {
      return c.Render(200, r.HTML("secure/index.html"))
    })
// Create a logout action, where the userID inside the session is deleted
secure.DELETE("/logout",
    func(c buffalo.Context) error {
        session := c.Session()
        session.Delete("userID")
        session.Save()
        return c.Redirect(301, "/login")
    })
