Eine alte URL-Struktur meiner Website lautet wie folgt:

https://example.com/login.php
    or, 
    https://example.com/login.php?redirect=https://example.com
    or,
    https://example.com/register.php

Nachdem die URL neu erstellt wurde, sieht die URL so aus:

https://example.com/login
    or, 
    https://example.com/login?redirect=https://example.com
    or,
    https://example.com/register

Wenn ein Benutzer/Besucher nun die alte URL verwendet, https://example.com/login.php 时，我想重定向到 https://example.com/login die Seite. was soll ich machen?
