Simple HTTP Server in C

This is a simple HTTP server written in C that provides basic functionality for handling HTTP requests. It is designed to handle the following features:

• Echo Route: Echoes back whatever comes after the "/echo" route in the request.
• User-Agent Route: Displays the User-Agent header received from the client.
• File Serving: Serves files if requested by the client. If the requested file exists, it is sent to the client; otherwise, a 404 error is returned.
• Invalid Request Handling: Responds with a 400 error for invalid requests.

Prerequisites

• C compiler (e.g., gcc)
• GLib library (GLib Official Website)

Installation

1. Clone the repository:

   git clone https://github.com/hugo-russeil/http-server.git

2. Compile the server:

   make

3. Run the server:

   ./server

4. Once the server is running, you can send HTTP requests to it using tools like cURL or web browsers.

Usage

• Echo Route: Accessible via /echo. Anything after /echo in the URL will be echoed back in the server's response.

  Example:

  GET /echo/helloWorld HTTP/1.1
  Host: 127.0.0.1:8080
  

  Response:

  helloWorld
  

• User-Agent Route: Accessible via /user-agent. Displays the User-Agent header received from the client.

  Example:

  GET /user-agent HTTP/1.1
  Host: 127.0.0.1:8080
  User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:97.0) Gecko/20100101 Firefox/97.0
  

  Response:

  User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:97.0) Gecko/20100101 Firefox/97.0
  

• File Serving: Any other route will be interpreted as a request for a file. If the requested file exists, it will be sent to the client. Otherwise, a 404 error will be returned.

  Example (assuming index.html exists):

  GET /index.html HTTP/1.1
  Host: 127.0.0.1:8080
  

  Response (if index.html exists):

  Content of index.html

  Response (if index.html does not exist):

  404 Not Found
  

• Invalid Request Handling: The server responds with a 400 error for invalid requests.

  400 Bad Request
