To Understand Client-Server Communication Via Sockets

To Understand Client Server Communication Via Sockets To Gain Ex

Develop a multithreaded Web server and a simple web client that communicate using HTTP. The server should listen on a specified port (default 8080), handle multiple HTTP GET requests concurrently in separate threads, and respond with the requested web page or an appropriate error message. The client should connect to the server, request a page, and display the response status and content. Both programs should be executable from the command line with optional parameters for IP address, port number, and file path. Submit a zipped package containing source code, any necessary files, and a readme with instructions, including the development environment details. Proper documentation of code and acknowledgment of external sources are required.

Client-server communication via sockets is fundamental to web technologies, enabling the exchange of data between clients (browsers) and servers (web hosts). Implementing a multithreaded web server and a simple web client provides practical insights into how HTTP requests and responses are managed over TCP connections.

The core component of this project involves developing a multithreaded web server capable of handling multiple concurrent requests. This is critical because real-world web servers must manage numerous users simultaneously without performance degradation. The server will listen on a specified port, commonly port 8080, and upon receiving an HTTP GET request, it will spawn a new thread to process and serve the request. This threading approach ensures the main server thread remains responsive to incoming requests.

In terms of functionality, the server must interpret the request headers, log request details for debugging purposes, and return the appropriate HTTP response. If the requested file exists, the server responds with "HTTP/1.1 200 OK" followed by the page content; otherwise, it must return an error status such as "HTTP/1.1 404 Not Found" or "HTTP/1.1 400 Bad Request." When no specific page is requested, the server should serve a default page, typically "index.htm." The server’s design should adhere to HTTP message standards, with clear request and response formats.

The client program complements the server by establishing a socket connection to the server's IP address and port. It sends an HTTP GET request for a specified file or defaults to "index.htm" if none is provided. After receiving the server’s response, the client extracts the status line and page content, displaying or logging them appropriately. This operation helps illustrate the request-response cycle fundamental to web communication.

Implementation choices are flexible; the project may be developed using any programming language, with Java and Python being popular options due to their socket programming support. Utilizing skeleton code or prior references can facilitate development but must be well-documented to ensure clarity. Submission requires packaging all source codes, supplementary files needed for execution, and a readme file detailing setup, compilation, and run instructions, including environment specifics.

Adherence to academic integrity is vital; sources from external code and literature must be properly acknowledged. The project emphasizes understanding socket programming, HTTP message structures, and multithreaded server design, providing practical experience in these areas that are central to modern web development and network programming.
