Since PowerBuilder 2017 R2, we have a new HTTPClient object, which is a base object for sending HTTP requests and receiving HTTP responses from a resource identified by a URI. Compared to the Inet object, the HTTPClient object is easier to use and supports more methods (Get/Post/Put/Delete) and more SSL protocols (TLS 1.0, TLS 1.1, TLS 1.2, SSL 2.0, and SSL 3.0).
Among other things, the HTTPClient can be also used to consume SOAP Web services. This is particularly useful as the Web Service Proxy has many limitations and defects calling SOAP Web services such as not supporting TLS 1.2. This article is to show how you can use the new HTTPClient to call your existing SOAP Web services instead.
