Enumeration Type Documentation

enum CHAT_MAX_CLIENT_UPDATES

jsupdated.php - notes by Martin Langhoff <martin@catalyst.net.nz>

This is an alternative version of jsupdate.php that acts as a long-running daemon. It will feed/stall/feed JS updates to the client. From the module configuration select "Stream" updates.

The client connection is not forever though. Once we reach CHAT_MAX_CLIENT_UPDATES, it will force the client to re-fetch it.

This buys us all the benefits that chatd has, minus the setup, as we are using apache to do the daemon handling.
