Hello,

We are in process of implementing Azure Blob storage for Media for Umbraco version 8.1 as suggested in https://our.umbraco.com/Documentation/Extending/FileSystemProviders/Azure-Blob-Storage/index-v8

This works perfectly fine when using the account Name and account key in the config for "AzureBlobFileSystem.ConnectionString:media".

We are now trying to implement Shared Access Signature URL and tried putting in the values "AzureBlobFileSystem.ConnectionString:media" as recommended in https://docs.microsoft.com/en-us/azure/storage/common/storage-configure-connection-string

sample format used as below

• BlobEndpoint=https://storagesample.blob.core.windows.net; FileEndpoint=https://storagesample.file.core.windows.net; SharedAccessSignature=sv=2015-07-08&sig=iCvQmdZngZNW%2F4vw43j6%2BVz6fndHF5LI639QJba4r8o%3D&spr=https&st=2016-04-12T03%3A24%3A31Z&se=2016-04-13T03%3A29%3A31Z&srt=s&ss=bf&sp=rwl

• BlobEndpoint=https://storagesample.blob.core.windows.net; SharedAccessSignature=sv=2015-04-05&sr=b&si=tutorial-policy-635959936145100803&sig=9aCzs76n0E7y5BpEi2GvsSv433BZa22leDOZXX%2BXXIU%3D

But we are facing 403 error. Can you kindly confirm SAS can be used to connect to Azure blob from Umbraco and if Yes, kindly share the expected format for using SAS

Thanks.
