Python Django strangely does mapping towards unexpected URL

Question

I tested 1st Django web app project.
That app project redirects to http://127.0.0.1:8000/api/ when the URL of http://127.0.0.1:8000 is visited. The test was successful.

And then, I tested 2nd Django web app project.
That Django app should have redirected to http://127.0.0.1:8000/blog/ when the URL of http://127.0.0.1:8000 is visited but Django strangely redirects to http://127.0.0.1:8000/api/ which was target URL of 1st Django web app.

There is no /api/ URL configuration in 2nd project
Following code snippets are URL configuration of 2nd Django web app

# AskDjango_webfrontend_begin/askdjango/urls.py
urlpatterns = [
    path('admin/', admin.site.urls),

    # If the client enters in "localholst:8000", the page is redirected to localholst:8000/blog/
    path("", RedirectView.as_view(url="/blog/", permanent=True)),

    # If the client enters in "localholst:8000/blog/", connect to blog.urls.py
    path("blog/", include("blog.urls")),
]

# AskDjango_webfrontend_begin/blog/urls.py
urlpatterns = [
    path("",views.index,name="index"),
    path('<int:pk>', views.post_detail, name="post_detail")
]

Answer 1

Your browser has cached the 302 Redirect HTTP response from the first URL. Clear your cache and try again.

I recommend you to use different hostnames (such as 127.0.0.1 and 127.0.0.2 ) while testing multiple web applications running on the same development PC.
