I have a proposal for implementing virtual hosting in IRC and NNTP (if it does not already have them). The HOST command takes one argument being a domain name in ASCII format, and will cause the server to treat as though the client is trying to connect to the server with the specified name (like "Host:" in HTTP). The port number is not specified, because the server already knows what port number the client tried to connect to. The HOST command cannot be used with TLS (use SNI instead if you are using TLS) nor can it be used in combination with the STARTTLS command. In IRC, HOST must precede USER and NICK if virtual hosting is used. In NNTP, HOST will reset the state of the connection if it is successful, and the server responds by 200, 201, 400, or 502, as appropriate, just as though it is a new connection. HOST should be used before any other commands since the capabilities etc might be different for different virtual hosts and because authentication, etc will probably be different so you will have to make any authentication and other state after you specify the domain name rather than before. -- Don't laugh at the moon when it is day time in France.
