Using runtime shared library assets involves two procedures. First, the author of the source document defines a shared asset in the source document and enters an identifier string for the asset and a URL (HTTP or HTTPS only) where the source document will be posted.
Second, the author of the destination document defines a shared asset in the destination document and enters an identifier string and URL identical to those used for the shared asset in the source document. Alternatively, the destination document author can drag the shared assets from the posted source document into the destination document library. The ActionScript version set in the Publish settings must match that of the source document.
In either scenario, the source document must be posted to the specified URL for the shared assets to be available for the destination document.
