' To upload a file we're simply sending a PUT with the content of the data.  For example:

' PUT https://myaccount.blob.core.windows.net/pictures/photo.jpg?sv=2015-02-21&st=2015-07-01T08%3a49Z&se=2015-07-02T08%3a49Z&  sr=c&sp=w&si=YWJjZGVmZw%3d%3d&sig=Rcp6gQRfV7WDlURdVTqCa%2bqEArnfJxDgE%2bKH3TCChIs%3d HTTP/1.1  
' Host: myaccount.blob.core.windows.net  
'   
' Content-Length: 12  
'   
' Hello World.  

' Upload a string to a helloWorld.txt file in the "mycontainer" container, in the "chilkat" account.
