If a Shiny application contains embedded applications (loaded in iframes), each of those embedded applications loads a separate copy (via a distinct URL) of resources that should be shared (bootstrap, fontawesome, etc).
These resources should all map to the same top-level location, thus allowing the browser to use its cache and reduce the amount of network pressure.
