title: Max length on a SAS of Azure
body: <p>I have been looking at Azure Storage Documentation but I could not find a way to limit the size of a blob when using a SAS. I can set the duration and the type of it but no the size. Do you know any way?  </p>
  
  <pre><code>var sharedAccessPolicy = {
      AccessPolicy: {
          Permissions: azure.BlobUtilities.SharedAccessPermissions.WRITE,
          Start: startDate,
          Expiry: expiryDate
      },
    }
  </code></pre>
  
  <p>Thank you</p>
