title: Avoid over-writing blobs AZURE
body: <p>if i upload a file on azure blob in the same container where the file is existing already, it is over-writing the file, how to avoid overwriting the same? below i am mentioning the scenario...</p>
  
  <p>step1 - upload file "abc.jpg" on azure in container called say "filecontainer"</p>
  
  <p>step2 - once it gets uploaded, try uploading some different file with the same name to the same container</p>
  
  <p>Output - it will overwrite existing file with the latest uploaded</p>
  
  <p>My Requirement - i want to avoid this overwrite, as different people may upload files having same name to my container.</p>
  
  <p>Please help</p>
  
  <p>P.S.</p>
  
  <p>-i do not want to create different containers for different users</p>
  
  <p>-i am using REST API with Java</p>
