getRemoteHost() returns ""
I thought I could get the remote hostname in a Servlet
or jsp file. The following returns nothing for getRemoteHost():
<FORM>
HostIP="<%= request.getRemoteAddr() %>"
<INPUT TYPE='text'
NAME='hn'
VALUE="<%= request.getRemoteHost() %>"
SIZE='15'>
</FORM>
</html>
I was suspecting it is a name resolution (DNS) problem but my
nameresolution sequence is hosts, then bind. And the host 192.168.1.119
for example (it's an intranet) can be found.
Any clues?

I'm still using 3.1 beta. I just found that the Snoop servlet exposes the
same behaviour.
When I would upgrade to 3.2b7 (or what that is at the moment), what
differences would I have to expect?
Could I migrate the webapps tree and tomcat-apache.conf seamlessly?

What version of Tomcat are you trying this with? It appears to work fine
for me with 3.2b7 and 4.0m4, as long as DNS is correctly configured on the
machine that Tomcat is running on.
