I noticed that many websites, when they redirect you, they show a "redirecting in 5 seconds" page before the actual redirection. What's the purpose of that?
I am currently implementing a links directory and I made it so that the redirection happens instantly via a 301 redirect header response. Why would I want to add that extra loading time? It's not like it would help with website load, actually the contrary as a full page has to load instead of just the response headers.
