Since I seem to have touched off this thread, I would clarify by saying
that:
getRemoteAddr() returns the I.P. address, but getRemoteHost() returns
nothing.
I assume that
1 - getting the I.P. address is easy, since is should be sent to the host,
to get a response;
2 - getting the host name (domain name) requires a call to another server,
and may not be readily available
A work-around would be to make a call to one of the servers that offer a
domain name look-up, and use that.
