Java webserver implementation mostly without any external dependencies (only jetbrains annotations).
- HTTP/2
- GET, POST, HEAD, PUT, DELETE, OPTIONS, TRACE, CONNECT
- Middlewares
- Routes
- Static files serving
- Reflection routers parsing (define page with using method annotation)
- Cookies
- Websockets
- Chunked transfer encoding
- GZIP compression
- Basic authentication
- Sessions
- Logging
- Error pages
