• TCP events: TCP_ACCEPTED, SERVER_CONNECTED, SERVER_BEFORE_CONNECT

when TCP_ACCEPTED {	
	AFTER_TIMER_NAME = function ()		
	debug("[%s]====>After function call begin:\n",ctime());
	debug("[%s]====>After function call end.\n",ctime());
end

TCP:after_timer_set("AFTER_TIMER_NAME", 1000, true);
}
when HTTP_REQUEST{
    debug("[%s]------> Events: HTTP_REQUEST begin:\n", ctime());
