PHP is changed to. html or. shtml, in which case, if not redirected, the user's favorites or the old address in the search engine database will only give access to a 404-page error message, and the access traffic is lost; and some sites that are registered with multiple domain names, You also need to redirect users who access these domain names to the main site automatically, and so on.
