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

# Connect to the destination web server.

# This example will send the following multipart/form-data request.
# The Content-Length is automatically computed and added by Chilkat.
# It will be different than what is shown here.
# The boundary string is also generated by Chilkat and will be different
# than shown below.
