Prevent hot linking for get_serving_url() in Google App Engine

Question

Is there a way to prevent hot linking for images that are served by the Images Service method get_serving_url()?

I only found this answer but I don't think it would apply to get_serving_url().

No - If you want any kind of access control for images you're serving from Blobstore/Google Storage then you should write a BlobstoreDownloadHandler and use send_blob to return the image after doing whatever access control you would like.

If you're using the crop or resize options of get_serving_url() then you would need to do this transformation yourself and store the result in blobstore, which is what you would then return.

No, you cannot do referrer checks on blobstore or image service URLs.
