Hi Steinar,

I could ask you to 'prove it', too, but I can easily check when I get back =
from my current travels :-)

It important to note that even if it does (as I think it does) it is NOT in=
 violation of the RFC. The RFC simply says that if a client wants something=
 it should ask for it, and not that a server cannot send the options unsoli=
cited.

Best regards,

John
