Please allow me introduce a mod_perl based chat service at http://www.waterlet.com/b/public/e/room
Use Apache, Mod_Perl and Javascript only, no Java, yet no "refresh" or "reload" of the page. New messages will be polled using Javascrip and be inserted smoothly into the chat window. So far, I did not see such a service in mod_perl. There are few in PHP though (actually, there is a library for Chat sevice in PHP). I'd like to see if the community is interested in the idea and if to pack it to website for public use. Some technical features: 1) a light Apache on the frontend, taking care authentications for registered members or anonymous ones. 2) a mod_perl on backend, taking care all other operations. Messages and status data are shared by IPC::MM. 3) only new message data will be deliver to clients. The estimated maximum capacity is about 10 rooms of average 100 chatters in a room, providing that the apache delivers 1000 - 2000 hits per second. Let me know. info AT waterlet DOT com
