Question checking the heartbeat of the online user

hello,
Can anyone please tell me how can i check the availability of the online user in a client-server environtment.
This is for a program where lakhs of client are connected to the server and the server has to check the availability of the every client in every minute.
So polling every client is not a good option.
Can anyone help me for the solution.

NAME
mooproxy - a buffering proxy for MOO connections SYNOPSIS
mooproxy [options] DESCRIPTION
mooproxy is a buffering proxy for MOOs (a class of text-based RPGs, descending from MUDs). The MOO client connects to mooproxy, and mooproxy connects to the MOO server. Mooproxy keeps you connected to the MOO server if the client disconnects (voluntarily, because of network problems, because the client crashes, because of a power outage, etc). Mooproxy also provides centralised logging, buffers text when the client isn't connected, and provides context when the client does con- nect. OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. -h, --help Show summary of options and exit. -V, --version Show version information and exit. -L, --license Show licensing information and exit. -w, --world worldname Specify the world file to load. -d, --no-daemon Do not daemonize; stay in the foreground instead. -m, --md5crypt Prompt for a string, and create and show an MD5 hash of this string.
