As a complement to my last answer, one of the reasons I want to set a custom Content-Type value is because we include versioning in our custom media types (I skipped this part to simplify my example code in earlier mails). We simply want to use Content-Type to show the type and version of the data returned from our REST service.
However, as long as I can't figure out how to set "contentTypeHeader" to false (for the DataFormat implementations internally used by REST DSL routes), the custom Content-Type value (which I explicitly set in the route) will always be overriden to either "application/xml" or "application/json". Is there a way to configure "contentTypeHeader" when implementing a route using REST DSL? If not, is there a reason why not? Thanks in advance, Calle
