If you can provide the right URL on output, then Interchange will work
fine. I am still very unclear on what you are trying to accomplish.
If you want to use the same catalog.cfg file, then you will need
to have a way to determine what the outputted URL is for that
You may not know that you can do something like:
interchange -restart construct:VendURL=http://machine1/cgi/script
interchange -restart construct:VendURL=http://machine2/cgi/script
The other possible way is to have a separate ConfDir
(i.e. /usr/local/interchange/etc) for each machine, and use the
etc/construct.after configuration file to modify configuration.
You might have to get some consulting help, but it can be done, that
