All of the Lua code injected by rewrite_by_lua*, access_by_lua*, and
content_by_lua* is already running in a Lua coroutine created
automatically.

One way to implement comet servers atop ngx_lua, you can use redis's
pub/sub API with the lua-resty-redis library. You should also
configure the lua_check_client_abort directive (and possibly set a
callback for ngx.on_abort), as well as configuring TCP keepalive
properly in your system's TCP stack implementation.

Please check out the ngx_lua's official documentation for more details:
