Hello World Server

Task

Implement a simple HTTP server that responds with “Hello, World!” to any request.

• Use the provided http-server.h library
• Implement the handle_request function
• Always respond with “Hello, World!” regardless of the request

Function Signature

void handle_request(char *request, int client_socket);

HTTP Response Format

A minimal HTTP response consists of:

HTTP/1.1 200 OK\r\n
Content-Type: text/plain\r\n
\r\n
Hello, World!

Important

Use \r\n (carriage return + newline) for line endings in HTTP, not just \n.

Note

• Use send(client_socket, data, length, 0) to send data to the client
• Use strlen() to get string lengths
• You can build the response as one string or send it in pieces
• Include <string.h> for strlen()

---

Example

For any request (e.g., GET /hello HTTP/1.1 or GET /test HTTP/1.1):

Your server should respond with:

HTTP/1.1 200 OK
Content-Type: text/plain
 
Hello, World!

Test Locally

$ gcc -o hello_world_server hello_world_server.c http-server.c
$ ./hello_world_server
Server started on port 8000
 
# In another terminal:
$ curl "http://localhost:8000/hello"
Hello, World!
$ curl "http://localhost:8000/anything"
Hello, World!

Code

#include "http-server.h"
#include <string.h>
 
void handle_request(char *request, int client_socket)
{
    char* data = "HTTP/1.1 200 OK\r\nContent-Type: text/plain\r\n\r\nHello, World!";
    send(client_socket, data, strlen(data), 0);
}
