REQUEST['SCRIPT_NAME'] is the root of the Zope server. In a pure ZServer
environment, this is '/'. In a situation where the Zope server is running
behind another webserver, and is not at the root of that server,
SCRIPT_NAME represents the path to the Zope server.

For instance, if your Zope server is presented to the outside world as
'http://a.server.com/a/path/to/zope/' then SCRIPT_NAME will be
'/a/path/to/zope/', whereever you are in the Zope object hierarchy.

Thus, a version cookie is bound to the root of the Zope server. In your
case, it seems that Opera is ignoring the cookie path altogether, and
instead falls back on the default, which is the path of the Version object
itself.
