The HTTP protocol (Hypertext Transfer Protocol) is a communication protocol that allows communication between web servers and web clients (usually web browsers).
Here are the steps involved in how it works:
1. A web browser sends a request to a web server, asking for a specific resource (such as a webpage or an image).
1. The web server receives the request and processes it, looking for the requested resource.
1. If the resource is found, the server sends a response back to the browser containing the requested resource.
1. If the resource is not found, the server sends a “404 Not Found” response back to the browser.
1. The browser receives the response and begins to render or display the received content.
1. If the response includes other resources, such as images or CSS files, the browser sends separate requests for those resources to the server and repeats the process.
The HTTP protocol works over a TCP/IP network, and it uses specific methods, or HTTP verbs, to indicate the type of request being made. These verbs include GET, POST, PUT, DELETE, and others. HTTP also uses headers to provide additional information about the request or response, such as the content type or the length of the message.
