Deal with TTL for DCOR basin-based feature data #244

Open paulmueller opened 10 months ago

paulmueller commented 10 months ago

The dcserv version 2 API generates a pre-signed URL for accessing a resource via the HTTP format. However, this pre-signed URL as a finite lifetime after which it becomes invalid. The DCOR file format should identify the lifetime and replace the basins automatically upon expiration.

Here is one of the error messages that may appear in Shape-Out 2 after the presigned-url times out.

Unhandled exception in Shape-Out version 2.15.0:
