There is a website that occasionally stupidly redirects with HTTP Status 301 (“Moved Permanently”) its login page to a “maintenance” page.
I tried to visit this page while the redirection was effective, so Firefox cached it. Now, the redirection is not effective anymore, but, when I want to visit the login page, Firefox sees the cached redirection and immediately shows me the “maintenance” page…
I checked the about:cache page and could check that the redirection was indeed cached. I hoped there would be a button to remove that cache entry, but did not find it.
I know I can clean the whole cached web content, but that sounds overkill.
I also know I can use the “forget about this site” feature from the history, but it would also forget the remembered credentials, which is somewhat troublesome.
So is there I can purge this specific cache entry?
(No need to tell me that the webmaster is a moron who does not understand the difference between temporary and permanent redirects, I know…)
