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

rest = chilkat2.Rest()

# Connect to the Azure Storage Blob Service

bAutoReconnect = True
# In this example, the storage account name is "chilkat".

# Set some request headers.

success = rest.AddHeader("x-ms-meta-m2","v2")

# Note: The application does not need to explicitly set the following
# headers: x-ms-date, Authorization, and Content-Length.  These headers
# are automatically set by Chilkat.

fileStream = chilkat2.Stream()

# The file is streamed, so the full file never has to completely reside in memory.

# When successful, the Azure Storage service will respond with a 201 response code,
# with an empty body.  Therefore, in the success condition, the responseStr is empty.
