In Cheshire (http://cheshire.berkeley.edu) we run a cgi oriented version
of our Z client which interprets the form, transforms it into a Z query
and rushes off to interogate the requested database(s).

So:

Web browser (submits form to) Z39.50 CGI Client (submits Z search to)
Z39.50 Database

Here the 'origin' is the Z CGI Client, the 'target' is the Z Database.

Some examples of our system in action, all of which fit the above scheme:
