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

# This example constructs and sends the following HTTP request.
# (The boundary strings will be different and auto-generated by Chilkat)

# Accept-Encoding: gzip,deflate
# SOAPAction: invio
# Content-Type: Multipart/Related; boundary="MIME_boundary"; type="text/xml"; start="mailto:rootpart@soapui.org"
# MIME-Version: 1.0
# 
# --MIME_boundary
# Content-Type: text/xml; charset=UTF-8
# Content-Transfer-Encoding: 8bit
# Content-ID: <rootpart@soapui.org>
#  
# <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:attachment.ws.it">
# <soapenv:Header/>
# <soapenv:Body>
#   <urn:inputBean>
#    <nomeFileAllegato>myfile.zip</nomeFileAllegato>
#   </urn:inputBean>
# </soapenv:Body>
# </soapenv:Envelope>
#  
# --MIME_boundary
# Content-Type: application/zip
# Content-Transfer-Encoding: binary
# Content-ID: <myfile.zip>
# Content-Disposition: attachment; name="myfile.zip"; filename="myfile.zip"
# 
# ... binary zip data goes here ...
