CDN Support for ERPNext

Hey Team,

is there any plan for CDN (Content Delivery Network) support? We plan to have our website accessible in two different locations (Germany, China). Does anybody have valuable input for creating such an extension? Could it be easily hooked into the already existing cache infrastructure? I think the most complex part would be a proper invalidation of updated content, but hopefully this is already solved.

I would appreciate if somebody could give me some pointers (e.g. current cache concept).
