TCP to HTTP Server

A minimal HTTP/1.1 server built from the ground up using raw TCP sockets in Go. This project was developed as part of the "From TCP to HTTP" course on boot.dev, focusing on understanding the fundamental protocols that power the web.

Features

Pure TCP implementation: No net/http package for core HTTP handling

HTTP/1.1 compliant: Implements the HTTP specification with proper message parsing

Chunked transfer encoding: Supports streaming responses with Transfer-Encoding: chunked

Trailer headers: Implements HTTP trailers for post-response metadata

HTTP proxy: Can act as a proxy to external services

Getting Started

Installation

# Clone the repository
git clone <repository-url>
cd tcptohttp

# Run the server
go run ./cmd/httpserver [port_number]

The port number argument is optional. If not provided, the server defaults to port 8000.

Once running, access the server at: http://localhost:8000

Available Routes

/

Welcome message with a simple text response.

/html-wrong

HTML response with a 400 Bad Request status code and humorous error message.

/html-server

HTML response with a 500 Internal Server Error status code.

/html-ok

HTML response with a 200 OK status code and sample content.

/httpbin

Proxies requests to https://httpbin.org using chunked transfer encoding. This endpoint demonstrates streaming responses and trailer headers with X-Content-SHA256 and X-Content-Length.

Example: GET /httpbin/stream/5 streams 5 JSON responses from httpbin.org.

/video

Streams a sample video file with proper chunked encoding, simulating a video streaming endpoint.

Need create dir assets and put .mp4 file in.
