SYNOPSIS

DESCRIPTION
Mojo::Server::Daemon is a full featured, highly portable non-blocking I/O HTTP and WebSocket server, with IPv6, TLS, Comet (long polling), keep-alive, connection pooling, timeout, cookie, multipart and multiple event loop support.
For better scalability (epoll, kqueue) and to provide IPv6 as well as TLS support, the optional modules EV (4.0+), IO::Socket::IP (0.16+) and IO::Socket::SSL (1.75+) will be used automatically by Mojo::IOLoop if they are installed. Individual features can also be disabled with the MOJO_NO_IPV6 and MOJO_NO_TLS environment variables.
See "DEPLOYMENT" in Mojolicious::Guides::Cookbook for more.
