When I run a query against the iTunes Search API over SSL, most of the URL's returned are provided via HTTPS:
https://itunes.apple.com/search?term=rihanna
However, the artworkUrl results are served over HTTP and updating them manually throws an error since the SSL certificate doesn't match on the domain they're using.
Is there a way to grab these images over HTTPS instead of HTTP?
iTunes does not support the album art or song previews over HTTPS (yet).
The change over of the tools and links to HTTPS was recent (only four months ago): http://www.apple.com/itunes/affiliates/resources/blog/secure-links-to-itunes---content-and-tools.html
