- The purpose of this is that in several django projects I have needed
- several specific views that need to support basic authentication, yet the
- web site as a whole used django's provided authentication.
-
- The uses for this are for urls that are access programmatically such as
- by rss feed readers, yet the view requires a user to be logged in. Many rss
- readers support supplying the authentication credentials via http basic
- auth (and they do NOT support a redirect to a form where they post a
- username/password.)

-
- @logged_in_or_basicauth
- def your_view:
- ...
-
- You can provide the name of the realm to ask for authentication within.
