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

Dim rest As New Chilkat.Rest

Dim port As Integer = 444
Dim bAutoReconnect As Boolean = True
Dim success As Boolean = Await rest.ConnectAsync("portal.mvp.bafin.de",port,bTls,bAutoReconnect)

' The SOAP request we'll be sending is multipart/related and it will have two parts
' 1) the SOAP Envelope
' 2) the MTOM attachment (in this case an XML document)

' Let's build the SOAP envelope:

' We want the top-most header of our request to look like this:

' POST https://portal.mvp.bafin.de:444/services/ws/t_a26mifir HTTP/1.1
' Content-Encoding: gzip
' Accept-Encoding: gzip,deflate
' Content-Type: multipart/related; type="application/xop+xml";
'    start="<rootpart@soapui.org>"; start-info="text/xml"; boundary="----=_Part_3_19706996.1467294979823"

' Transfer-Encoding: chunked
' Host: portal.mvp.bafin.de:444
' Connection: Keep-Alive
' User-Agent: Apache-HttpClient/4.1.1 (java 1.5)

' Some header fields are unimportant.  
' 1) We can omit the User-Agent.
' 2) Also, the Transfer-Encoding doesn't need to be "chunked".  It shouldn't matter whether it's chunked or non-chunked.
' 3) We do need the Content-Encoding to be "gzip", because the documentation at https://www.bafin.de/SharedDocs/Downloads/EN/dl_mvp-portal_soap_webservice_a26mifir_en.pdf
' explicitly states that it wants a gzip compressed request body.
' 4) Don't worry about specifying a boundary.  Chilkat will auto-generate a boundary and add it to the Content-Type.
' 5) If we're sending many requests on the same connection, then set the Connection: Keep-Alive header.  Otherwise, there is no need for it.

' Begin specifying header fields for the topmost header:
