Testing the Medical Web Viewer

Step 5 - Testing the Medical Web Viewer with the LEAD Sample External Store addin

• The Medical Web Viewer works with the external store addins. 
• 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
