# go-http-server

A minimal TCP-based HTTP server in Go for learning and experimentation. It demonstrates manual request-line and header parsing and simple connection handling.

Requires
- Go 1.26 or newer.

Quick start
1. Build
   - cd into the project root (the directory that contains `go-http-server`) and run:
     ```
     cd go-http-server
     go build -o go-http-server
     ```
2. Run
   - Start the server:
     ```
     ./go-http-server
     ```
   - Or during development:
     ```
     go run .
     ```

Testing
- Run unit tests:
  ```
  cd go-http-server
  go test ./...
  ```

What’s in the repo
- `main.go` — listener and connection lifecycle.
- `readheaders.go` — `readHeaders` and `parseRequestLine` logic; returns a `Headers` struct.
- `response_helper` — helpers for writing responses.
- `config` — runtime configuration (listen address, profiling toggle).

Notes
- The parser expects a request-line with exactly three tokens: `METHOD URI PROTO`.
- Header lines without a colon are ignored; values are trimmed.
- The server supports simple keep-alive behavior when the `Connection: keep-alive` header is present.

Contributing
- Open issues or PRs. Add tests for parsing or new behavior and run `go test ./...` before submitting.
