Step 5 - Testing the Medical Web Viewer with the LEAD Sample External Store Add-in
The Medical Web Viewer works with the external store add-ins.
Since the Medical Web Viewer is stateless, it can request a DICOM dataset multiple times.
For speed, the Medical Web Viewer uses the local store as cache.
The cache (local store) is cleared when the Scheduler Clears (i.e. deletes) the dataset from the local store
There is one case to see:
When the Medical Web Viewer requests a DICOM dataset that exists on the external store but NOT the local store, the datasets is Restored (i.e. copied) to the local store * In this instance, the Medical Web Viewer is using the local store a cache, until the Scheduler Clears (i.e. deletes) the dataset from the local store
