You can configure the Web Service Consumer transformation to use cookie authentication. The remote web service server tracks the web service consumer users based on the cookies. You can increase performance when a mapping calls a web service multiple times.
When you project the cookie port to a web service request message, the web service provider returns a cookie value in the response message. You can pass the cookie value to another transformation downstream in the mapping or you can save the cookie value in a file. When you save the cookie value in a file, you can configure the cookie as input to the Web Service Consumer transformation.
You can project the cookie output port to any of the Web Service Consumer transformation output groups.
