Slow down suspicious requests

Define a delay to be used when incoming requests match a rule you consider suspicious.

export default {
  async fetch(request) {
    // Define delay
    const delay_in_seconds = 5;
    // Introduce a delay
    await new Promise((resolve) =>
      setTimeout(resolve, delay_in_seconds * 1000),
    ); // Set delay in milliseconds


    // Pass the request to the origin
    const response = await fetch(request);
    return response;
  },
};
