seHTTPd

seHTTPd implements a small and efficient web server with 1K lines of C code. I/O multiplexing is achieved using epoll.

Features

  • Single-threaded, non-blocking I/O based on event-driven model
  • HTTP persistent connection (HTTP Keep-Alive)
  • A timer for executing the handler after having waited the specified time
