When setting the responseActionType, such as "default" or "soap-fault", to a value that has an expected related unmodifiable responseContent value, the expected responseContent is not set. As a result an empty response page is returned when ASM blocks a request.
An empty response page is returned when ASM blocks a request.
Via ASM REST a client changes the responseActionType from "custom" to "default" or "soap-fault".
The alternate response body can be set explicitly via REST
Expected responseContent is now set when changing responseActionType to a static content type like "default" or "soap-fault" using ASM REST.
