With 7.11, Mendix added the ability to create or retrieve response headers only for REST calls. It would be great if the same functionality can be extended for web service calls as well.
We have a scenario where we need to read JSESSIONID from response and pass it back in subsequent requests.
Mendix 7.19 introduces a new feature that will allow you to do that. After the Call Web Service action, you can use the $latestHttpResponse variable. Use a Retrieve action to retrieve the headers.
