Thanks for your Answer Eric. But, we do not use a CDN.
What we tried in our specific project was to modularize our applications in a way that specific Polymer elements are delivered by dedicated servers (so they have a dedicated URL). A kind of dashboard imports these elements to provide a common/combined UI. Anyway, I see that there is no way to do this, except to use full URLs for import or do some kind of build step. best Christopher Am Montag, 23.
