I have already searched through the knowledge base for this header value with no results. Specifically this article doesn't have clear documentation or a clear path to explore to find the answer https://docs.microsoft.com/en-us/rest/api/cosmos-db/common-cosmosdb-rest-response-headers
I am getting this value in the last_response_headers dictionary within the CosmosClientConnection object belonging to the ContainerProxy object I'm instantiating while using the azure-cosmos python library.
