What I would like to be able to choose a group of IP addresses or machine
names and have them all run the same catalog. Machine1 is the orginal
machine. I would like to be able to choose from every IP address aliased
to the one physical address and run the interchange server on each of
them. I may have 10,000 virtual machines from the one physical interface,
but I only have 9,900 unique IP address or DNS entries. What I would like
to do is choose Name1, Name2, Name3,... or WWW.XXX.YYY.ZZ1, WWW.XXX.ZZ2,
WWW.XXX.YYY.ZZ3,... where each of these machines has only one location for
the catalog. i.e. from the catalog.cfg file
Variable SERVER_NAME machine1, machine2, machine3, machine4, ...
Variable SERVER_NAME host1, host2, host3, host4, ...
and the same for other variables like
Variable SECURE_SERVER http://machine1, http://machine2, ...
Variable SAMPLEURL http://machine1/construct, http://machine2/construct, ...
As I understand now I have to have a seperate catalog.cfg file for each
one, but they all have only one location with the same catalog.cfg. I can
change the catalog.cfg to work with any one of the virtual hosts, but not
more than one. So I am asking to be able to have more than one.
These may have all the same IP address for each host, but I want to select
from a group of hosts that all have the exact same location for
I do not get anything in the logs. I just get page not found error from
the webserver when I try http://host2/cgi-bin/user_store if I have
catalog.cfg configured for host1. Note the webserver is looking at the
same location for each. Does that make it clearer?
