Posted: Sun Apr 20, 2025 3:51 am
Whenever you access a page through a browser, the browser sends a request to the website's server. This communication between browser and server is carried out via HTTP (Hyper Text Transfer Protocol). The server then delivers two things, if possible:
the contents of the page or a predefined alternative (404 page or redirect)
the status of the requested page as an HTTP status code
e.g. 200: OK , 301: Redirected , or 404: Not Found
