Cannot send a redirect with a Location header

[stcarrez]

After a POST it is often necessary to use a redirect to another location. For a simple form submission, this is a best practice to avoid problems after the form is submitted.

A redirect needs either a 302 or 307 with a Location header.

One way to do it could be to add:

function Location (This : Response) return String;

and to handle that new response function in the Respond procedure.
