Description

When a ResourceStreamResource is implemented to return a IResourceStream dynamically, by returning a new instance of an extended AbstractResourceStream, that ResourceStream is instantiated multiple times when a ResourceLink is clicked.

In my case, that ResourceStream returns an AttachmentInputStream from the Ektorp library (for CouchDB interaction). This behavior results in multiple queries (currently up to four) when I click once on a ResourceLink to that resource.
