Description

Redirects to another page and action after disabling HTTP caching.

This effectively implements the "POST-Redirect-GET" pattern (also known as the "GET after POST").

The redirect() method is often called after a successful POST operation, to show a "success" or "edit" page. In such cases, clicking clicking "back" or "reload" will generate a warning in the browser allowing for a possible re-POST if the user clicks OK. Typically this is not what you want.

In those cases, use redirectNoCache() to turn off HTTP caching, so that the re-POST warning does not occur.

This method calls setNoCache() to disable caching.
