The operation principle of HTTP client and HTTP server is based on the client-server model. In this model, the client sends a request to the server, and the server responds with a corresponding response.
HTTP Client:
1. The client initiates a TCP connection to the server on port 80 (or another port designated for HTTP traffic).
2. The client sends an HTTP request to the server, specifying the method (GET, POST, PUT, DELETE, etc.), the URL, and any additional headers or data.
3. The client waits for a response from the server.
4. The server processes the request, generates a response, and sends it back to the client.
5. The client receives the response and processes it, which may include rendering HTML, downloading files, or executing scripts.
HTTP Server:
1. The server listens for incoming TCP connections on port 80 (or another designated port).
2. When a client connects, the server accepts the connection and reads the HTTP request.
3. The server processes the request, which may include accessing databases, generating dynamic content, or serving static files.
4. The server generates an HTTP response, including the status code, headers, and any content.
5. The server sends the response back to the client over the established TCP connection.
6. The server closes the connection, or keeps it open for subsequent requests.
