The Problem

In Django, when you return a custom 404 view, Django expects the HTTP response to have a 404 status code to signify "Not Found." However, if you don't explicitly set status=404 in the response, Django will treat it as a 200 OK response, even though you intended it as a "page not found" view.

It Misleading HTTP Response: Without status=404, the page will return 200 OK, which signals that the request was successful, misleading both users and search engines.

If you are using custom 404 template

from django.shortcuts import render

def custom_404_view(request, exception):
    return render(request, '404.html', status=404)  # Set status=404 here

Solution without Template

from django.http import HttpResponseNotFound

def custom_404_view(request, exception):
    return HttpResponseNotFound("Custom 404 page not found")

This behaviour is controlled by the APPEND_SLASH setting. In the default setting APPEND_SLASH is set to True which means if the requested URL does not match any paths set in urls.py an HTTP redirect will issue to the same URL with a trailing slash.

Eg: Assume a request to /foo.com/bar will redirect to /foo.com/bar/ in case the provided URL /foo.com/bar is an invalid URL pattern.

Documentation states that

Note that the redirect may cause any data submitted in a POST request to be lost.

The APPEND_SLASH setting is only used if CommonMiddleware is installed (see Middleware). See also PREPEND_WWW.

please read the documentation for further clarification.
