+# Login Redirect Middleware
+
+`LoginRedirectMiddleware` is a Middleware to be used when you want to create an automatic redirection from any routes when the user is not authenticated. Users that want to access to a protected route will be redirected to a single route.
+
+## Example
+In your main.swift file:
+
+```swift
+drop.grouped(LoginRedirectMiddleware(loginRoute: "/login")).group("admin") { routeAdmin in
+            let imagesViewController = ImagesViewController()
+            routeAdmin.get("images", handler: imagesViewController.indexView)
+            routeAdmin.get("images", Image.self, handler: imagesViewController.imageSelectedView)
+
+        }
+```
+
+> If the user is not connected when GET /admin/images is requested, user-agent will be redirected automatically to `/login` route
