-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- 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.

local success = http:http_str("PUT", url, "Hello World.", "utf-8", "text/plain", resp)
if not success then
    print(http.last_error_text)
