Yes, the
asterisks are a limitation of the free demo version. You would need to purchase a licence to remove this restriction.
As I said before, our product is not exactly a proxy discovery tool. The setting you mentioned will find open ports, but those are not guaranteed to be proxy ports, or that they will accept proxy connections.
You could either use the Remote Script feature and
- use an instance of "MSXML2.ServerXMLHTTP.6.0";
- or call console curl with the necessary parameters and analyse its response.
Or you could just find a proxy discovery/testing tool, there should be a few out there.
