One of the common issues with building sites over SSL is the mixed security warnings that occur when you reference images that are not in the same domain over a non-SSL connection. We're using Sencha.IO to access our images, so I thought it would be nice to be able to use it to reference a non-ssl image using the sencha url. It doesn't look like I can use https://src.sencha.io though. Is this something that's been considered?
