// Redirect
		if (page.redirect) {
			result.push('D');
			result.push(page.redirect);
			process.send(result.join(''));
			return;
		}

		// Using service name by default
		if (!page.state.Window.title) {

		consolidate.pug('views/index.pug', {
			cache: true,

			window: page.state.Window,
			state: JSON.stringify(page.state)
