Handling HTTP Requests
Write a basic Worker to intercept and respond to HTTP requests, demonstrating core functionality.
Workers and Web Requests
Cloudflare Workers are powerful tools that sit at the edge of the internet. Think of them as highly efficient gatekeepers for your web traffic.
Their primary job is to intercept incoming HTTP requests, process them using your code, and then send back an appropriate HTTP response.
Understanding the Request
Every time a user's browser interacts with your Worker, it receives a Request object. This object is packed with all the details about the incoming request:
- URL: The full web address the user tried to reach.
- Method: The HTTP action, like GET (fetching data) or POST (sending data).
- Headers: Extra information such as the browser type, cookies, and preferred language.
- Body: Any data sent with the request, common with POST or PUT methods.
