Hier noch was aus der R6 Designer Hilfe zum Thema IIOP:
For applications making remote (IIOP) calls based on the host server's Domino Directory, create an Internet Session object as follows, where hostString is the host name or IP address of the Domino server (not the Domino server name). The specification of a host name or IP address determines the use of the remote interface. A host name can be suffixed with the port number that the HTTP or DIIOP task uses to listen for TCP (non-SSL) connections using the syntax hostname:port (hostname-colon-port).
Note The ability to specify a port number is new with Release 6.
createSession(hostString, "", "") -- Anonymous Internet access is granted to the session if the host's Server record in the host's Domino Directory permits anonymous access. Parameter two must be an empty string, not null.
createSession(hostString, userString, passwordString) -- Internet access is granted to the session if the password matches the Internet password in the user's Person record in the host's Domino Directory.
Internet Sessions further restrict access according to the "Server Access" and "Programmability Restrictions" sections of the applicable Server record, and the "Maximum Internet name & password" section of the target database's ACL (Advanced tab).
