I agree that the ability to intercept and modify a request before it is sent to the server would be very useful.

I think that there is a script available that you can use to modify the "FindServers" and "GetEndpoints" responses so that your Java clients are forced to connect via the UACTT. In the script library you will find this script:

Start-FindServers-Intercept.js

That script should actually attach to GetEndpoints and FindServers and modify the results to point to the UACTT. Please try that and let me know if that helps you.

The problem i have is the UaExpert filling the EndpointURL parameter of the GetEndpoints request. The Java Server filters his available endpoints by some logic, using this parameter. Since the endpoint i connect to (Analyzer) is not the one of the Java Server, it returns no endpoints in the response and UaExpert does not connect. What i intend to do is to set the EndpointURL parameter to an empty string for all endpoints being returned.

Ah, I see. Hmm... How about another idea.. use the UACTT (Analyzer mode) to hard-code endpoints to return. It will not matter what the Java server returns because your script will just overwrite it anyway.

It's an ugly solution; but would be the quickest way to force the connection.

How's that sound?

yes, this would be possible, but it could be needed to load certificates into the endpoint description and would lead to a lot of scripting - the much easier way would be to just modify the EndpointURL parameter of the GetEndpoints call.

without adding the feature into the CTT this of course is a way to achieve what i intended.
