Where does request.getServerName get name from?
I know this is a simple question but just can't find the answer. I have two
instances of Tomcat running on one server. Each has a login page as the
entry point and that page includes a choice of databases. I'd like the
default database (i.e. one at top of select list) to be determined by
request.getServername(). The problem I'm having is that I'm getting a name
for one IP address and and IP address for the other. I can't figure out why
the second one won't give me a name. I can live with the IP address but I'd
prefer to get a name instead. Can anyone shed any light on where
request.getServerName() gets its name from?
I should add that the server name is in DNS correctly and enable lookups is
set to true.
Thanks for any info.

Without looking, it should be the same answer for the Coyote Jk2
Apache/IIS/iPlanet Connector. If it's not, then the bugs-that-never-die
hall-of-fame has just elected it's new queen ;-).

It depends very much on the precise configuration and Tomcat version
you're running. For standalone Tomcat 4.1.x running the Coyote HTTP/1.1
connector, it comes from the "host" header included with the request,
which in turn comes from your browser based on the URL you submitted to.
