smile when you say that..... and talk to a German who has a file name with a double-s in it..........As far as interoperability testing so far, my guess is that almost all testing so far has been with servers that implement case-sensitive comparisons. The exception would probably be the Hummingbird server, but I don't believe that most clients would be affected if a server's use of case-insensitive comparisons were somewhat non-standard.
