Rocket - Redirect to another page

---

• TODO: Implement the same in the separate files case.
• TODO: Redirect using other Status code
• TODO: Redirect to an external URL
• TODO: Optional redirction? (e.g. after successful login we redirect, but if it fails we would like to show the login page)
• TODO: Dynamic redirect. (e.g. after successful login we go to the page where the user really wanted to go)
