title: Azure storage blob upload from url
body: <p>Is there a way to do this? </p>
  
  <p>I have plenty of files over few servers and Amazon s3 storage and need to upload to Azure from an app (Java / Ruby) </p>
  
  <p>I prefer not to download these files on my app server and then upload it to Azure blob storage. </p>
  
  <p>I've checked the Java and Ruby sdk, it seems there's no straight way to do this based on the examples (means I have to download these files first on my app server and upload it to Azure)</p>
  
  <p><strong>Update</strong>:
  Just found out about <strong>CloudBlockBlob.startCopy()</strong> in the Java SDK.
  Tried it and it's basically what I want without using Third party tools like AzCopy.</p>
