This dataDriven loop (see below) needs to repeat and reset the proxy
each time through. However, after the first time through, it throws an
Unexpected exception caught: java.net.UnknownHostException
on the proxy, not the URL, at the invoke step, not the <setproxy .../>
step.
It is impossible to continue the subsequent tests after the first one
finishes successfully. If the code is altered to set the proxy outside
the dataDriven loop, it works fine up to the first failure.
It appears that the
.../steps.control.MultipleExecutionStepContainer.ProxiesResettingGroupSt
ep
class should be taking care of this inside the dataDriven loop but it
does not seem to be doing that.
Is there a way to make the <setproxy ... /> take and work without
writing new Webtest base code; I suppose writing would not be difficult
but building might?
The Groovy stuff in the <scriptStep ... />'s is working fine, returns a
Port number as the output from the <echo message=...> steps below
indicates.
The "HERE" in the <echo... />'s is to make grepping the messages out
easier.

LOTS OF ANT (not dynamic) PROPERTY SETTING CODE THAT IS WORKING FINE IN
OTHER APPLICATIONS. It is used inside the Groovy <scriptStep .../> code
as indicated below in the output from the <echo message= ... />
messages.

<echo message='HERE BEFORE GET PORT ${zeligPort} #{zeligPort}

The ${zeligPort} ANT Property is there
