http_c

A lightweight HTTP server written in C from scratch. Listens on port 8080, parses incoming HTTP requests, and routes them to the appropriate handler.

Build and Run

make ./server

Features

• Listens on 0.0.0.0:8080
• Routes GET, POST, PUT, DELETE requests
• GET — serves static files from assets/, routes / to index.html
• POST — creates or appends to a file in assets/
• PUT — overwrites a file in assets/
• DELETE — clears a file in assets/
• Returns proper HTTP status codes: 200, 201, 403, 404, 405, 500

Project Layout

• server.c — socket setup, accept loop, request parsing, response serialization
• handlers/req_handler.c — HTTP request parsing into structs
• handlers/res_handler.c — request routing and response generation
• handlers/routing.c — static file routing with content-type detection
• handlers/header_handler.c — HTTP header generation
• handlers/response_status_line_handler.c — status line generation
• include/ — shared data structures (request, response, header, body, status line)
• assets/ — static files served by the server
• Makefile — build and clean targets

Quick Test

# GET root
curl http://localhost:8080/

# POST a file
curl -X POST http://localhost:8080/test.txt -d "hello!"

# GET the file back
curl http://localhost:8080/test.txt

# PUT (overwrite) a file
curl -X PUT http://localhost:8080/test.txt -d "overwritten!"

# DELETE (clear) a file
curl -X DELETE http://localhost:8080/test.txt

TODO

• handle concurrent requests using threads or fork()
