Description Tomasz Cielecki 2017-02-15 11:53:29 UTC
Say I want to download an e-tagged Blob from Azure Blob storage, usually I would do that by setting a If-None-Match header with the e-tag I currently have (other headers are supported too: https://docs.microsoft.com/en-us/rest/api/storageservices/fileservices/Specifying-Conditional-Headers-for-Blob-Service-Operations?redirectedfrom=MSDN).

In case I already have the latest blob version I would get a 304 (Not Modified) status code, otherwise a 200 with the new file etc.

The problem here is that the AndroidClientHandler does not support the 304 Status Code and throws an InvalidOperationException


Would really love to be able to use this handler for Azure Blobs.
