     * Redirects to another route through 3 exception handlers.
     *
     * You will see "ExceptionHandler 1 loaded" 2 times. This happen because
     * the exceptionhandler is asking the router to reload.
     *
     * That means that the exceptionhandler is loaded again, but this time
     * the router ignores the same rewrite-route to avoid loop - loads
     * the second which have same behavior and is also ignored before
     * throwing the final Exception in ExceptionHandler 3.
     *
     * So this tests:
     * 1. If ExceptionHandlers loads
     * 2. If ExceptionHandlers load in the correct order
     * 3. If ExceptionHandlers can rewrite the page on error
     * 4. If the router can avoid redirect-loop due to developer has started loop.
     * 5. And finally if we reaches the last exception-handler and that the correct
     *    exception-type is being thrown.
