Domain Blocking Example

This example demonstrates how to block the default domain in a Next.js application using a edge function.

What This Example Does

This example shows how to:

• Block requests to the default domain (contentstackapps.com)
• Return a 403 Forbidden response for the blocked default domain
• Allow all other requests to pass through normally

How It Works

export default async function handler(request) {
  const currentUrl = new URL(request.url);
  const hostname = currentUrl.hostname;
  
  if (hostname.includes('contentstackapps.com')) {
    return new Response('Forbidden', {
      status: 403,
      statusText: 'Forbidden',
    });
  }
  
  return fetch(request);
}

# Build for production
