# MiniWeb Server in C
This is a minimalist implementation of a web server in C that serves files requested by clients over HTTP.
## Usage
1. Compile the code:
```bash
gcc socket.c -o socket
```
2. Run the compiled executable:
```bash
./C-WebServer
```
3. Open a web browser and navigate to `http://localhost:8080/index.html` to retrieve the contents of `index.html`.
## Description
This simple web server listens on port 8080 for incoming HTTP requests. Upon receiving a request, it extracts the requested file name from the HTTP request header, opens the file, and sends its contents back to the client.
## Implementation Details
- **Socket Creation**: The server creates a socket using `socket()` function provided by `sys/socket.h`.
- **Binding and Listening**: The server binds the socket to a specific address and port using `bind()` and starts listening for incoming connections using `listen()`.
- **Accepting Connections**: When a client connects, the server accepts the connection using `accept()`.
- **Receiving Request**: The server receives the HTTP request from the client using `recv()`.
- **Extracting File Name**: It parses the requested file name from the HTTP request.
- **Opening File**: The server opens the requested file using `open()` with read-only mode.
- **Sending File**: It sends the contents of the requested file back to the client using `sendfile()`.
- **Closing Connections**: After sending the file, the server closes the file descriptor and the client connection.
## Limitations
- This server does not support concurrent connections. It serves one client at a time.
- Error handling and security measures are minimal. This code is not suitable for production use without further enhancements.
- The server sends a fixed-size buffer of 256 bytes from the file. This limits the size of files that can be served.
