What is ctrlproxy?

Ctrlproxy is a so-called IRC proxy or BNC (bouncer). It keeps a permanent connection to one or more IRC servers. The user can then connect and disconnect his/her IRC client to the bouncer without actually disconnecting from the 'real' IRC server.

Any conversations (or parts of them) that happen on IRC while the user is disconnected can then be sent when the user connects again or asks for them explicitly.

It is also be possible to log in from multiple locations simultaneously while using one and the same nick name on IRC.
