CDN configuration in Bloomreach

Hi,

I am testing out CDN configuration for Bloomreach Developer Edition. See below for the configuration. However, the URL rewriting to CDN is not happening in the REST API calls for the images served. See the image configuration below.

I have the image URLs to be written back in the REST API responses to CDN URL

hst:cdnhost - //cdn.example.org

Thanks
