http basic authentication “log out”

Question

HTTP basic authentication credentials are stored until the browser is closed, but is there a way to remove the credentials before the browser is closed?

I read about

Answer 1

If you have control over the server code, you can create a "logout" function that replies "401 Unauthorized" regardless of the credentials given. This failure forces browsers to remove saved credentials.

I just tested this with Chrome 34, IE 11, Firefox 25 - using Express.js server and HTTP basic authentication.
