Server Commands/WEBIRC
Syntax: WEBIRC <password> <ignored> <realhost> <realip>
Used by web IRC applications such as CGI:IRC and Mibbit to provide the server the real host and IP for the user connecting through the web IRC application. <ignored> is currently ignored by the server but MUST be provided. You can put anything in it's place, typically "cgiirc" is used though.
Use of this command is restricted by W:Lines in the IRCd's config.
