I was using Azure CDN for theme files. Still am, but while every other call to the CDN uses the /blog/ container the CSS doesn't? Why not? container is set up. It will upload files to the CDN, emoticons work, uploaded files work.
I am using a CNAME of cdn.adamh.us, attachment files are being called from cdn.adamh.us/blog/wp-uploads... just as they should be. Emoticons are being called from cdn.adamh.us/blog/wp-includes... just as they should be. But my theme file (specifically the background) is being called from cdn.adamh.us/wp-content... NOT as it should be. Why is it no longer using the container??
