What is HTTP?

How does HTTP work?
HTTP follows a simple request-response model. When you type a URL into your browser and hit “Enter,” your browser generates an HTTP request that is sent to the web server hosting the website you want to visit. This request contains important information, such as the type of content your browser can handle and the specific page you’re looking for.
The web server receives the request, processes it, and prepares the appropriate HTTP response. This response includes the data you requested, which could be in the form of text, images, videos, or any other content your browser can display. The server then sends this response back to your browser, which interprets the data and renders the web page on your screen.
HTTP uses various methods, or “verbs,” to define the action that the client wants the server to perform. The most common ones are:
GET: Used to request data from the server, like retrieving a webpage.
POST: Used to submit data to be processed, often used in forms and when uploading files.
PUT: Used to update existing data on the server.
DELETE: Used to remove data from the server.
Additionally, HTTP responses include status codes that indicate the result of the request. For example, a status code starting with 2 (e.g., 200 OK) signifies success, while a code starting with 4 or 5 (e.g., 404 Not Found or 500 Internal Server Error) indicates an issue with the request or server.
