IRC server-Instant messaging?

[iota]

Hi masters,

I'd like to know which kind of languages IRC servers use to make instant messaging among users. How do they work?

Thanks for your time to read and your answer.

Messaging between two users is done on a private level -- they do not include the server itself. It's been a while since I've read RFC 1459 (Internet Relay Chat Protocol), but as far as I know, this is the case. Servers, on the other hand, use the same system to send out messages between individual users, or they can broadcast to all users.

Like I said, it's been a while since I've reviewed the RFC. You can check it out a http://www.rfc-editor.org and search for 1459 specifically. Also, 2812 and 2813 specifically focus on Client and Server protocol specifically.
