3066531 - Instantaneous "400 session timeout" when accessing WebGUI transactions through a Web Dispatcher

Symptom

When accessing the WebGUI through an SAP Web Dispatcher, an error page stating "400 session timeout" is displayed immediately.

Subsequent access attempts show the error:

        service tree "/default_host/sap/public/bc/its" is not available for HTTP access

Accessing the WebGUI bypassing the Web Dispatcher works.

The parameter "is/instname_encoding" is set at the profiles of the ABAP system behind the Web Dispatcher.
