For SSP Doc retrieval - do we need to query the SDS for provider ASID when the source ASID is in the pointer? Can we use that to safely populate the “Ssp-To” header value?
You should use the ASID from the pointer. If a pointer is retrievable via SSP, the producer will have provided their ASID details in the ‘context.related’ section of the pointer body. By using this ASID, you can avoid SDS querying.
