Found a temporary fix for this. I’ll be using this plugin in addition to yours:
https://www.ads-software.com/plugins/real-time-find-and-replace/
That way I can do a search/replace on the DreamObjects url and replace it with the DreamSpeed CDN url. I haven’t implemented it on the test site above, but I’m using it on two other sites in development and seems to be working like a charm!
I understand this would normally be speed issue, but these sites are highly precached so no real worry there. What do you think?
