// Check the URL for typos if (url.includes(‘typo’)) { // Redirect to the correct URL window.location.replace(correctURL); }

// Check if the page or resource exists if (pageExists) { // Serve the page or resource res.sendFile(page); } else { // Return a 404 error res.status(404).send(‘Page not found’); }
