Whats the best way to reload/redirect a page in PHP which completely removes all history/cache? Which headers should I use?

What happens:

On clicking a link, get-parameters is set and a script is executed. When finished, I want to redirect and reload the page without the get-parameters. At first, it looks like nothing has happened, but when pressing F5, the changes appear.

What I want:

Redirect and reload so the changes appear without pressing F5.
