ELI5: Why do some websites say "Webpage moved: Redirecting in 10 seconds. Click here to redirect now." Why don't they just redirect immediately?

The actual redirect is being caused by a "tag" that the developer inserts into the code. They can customise it as much as they want, from 0 seconds to 100,000 seconds. But most developers choose 5 or 10 for two reasons:

1. It gives the user time to read the message (if they're interested) so that they *know* what is happening. Otherwise it may look like your browser has been randomly hijacked.

2. If you add an *instant* redirect, your "back button" becomes almost useless. Every time you try to go back, it will just *instantly* throw you forward again.
