I just double checked the 2.1 spec. The api docs say:
getRemoteHost
public java.lang.String getRemoteHost()
Returns the fully qualified host name of the agent that sent
the request. Same as the CGI variable REMOTE_HOST.
nothing about returning the IP instead of blank, so I think it's
ok for the 2.1 containers to return an empty string (or maybe null?).
In fact, you could probably stretch the spec to allow always
returning an empty string no matter what. That's the safest thing
to assume in any case.
