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

Chilkat.Rest rest = new Chilkat.Rest();

// Connect to portal.mvp.bafin.de:444
bool bTls = true;
int port = 444;
bool bAutoReconnect = true;
bool success = rest.Connect("portal.mvp.bafin.de",port,bTls,bAutoReconnect);
if (success != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

// 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:
// Note: The data posted here, including the username, are not actual accounts.  It is the sample data provided
// at https://www.bafin.de/SharedDocs/Downloads/EN/dl_mvp-portal_soap_webservice_a26mifir_en.pdf

// 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"
// SOAPAction: "http://www.bafin.de/mvp/a26mifir/submitDATTRA"
// MIME-Version: 1.0
// 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:
rest.AddHeader("Content-Type","multipart/related; type=\"application/xop+xml\"; start=\"<rootpart@soapui.org>\"; start-info=\"text/xml\"");
rest.AddHeader("Content-Encoding","gzip");

rest.AddHeader("MIME-Version","1.0");
rest.AddHeader("Connection","Keep-Alive");

// ------------------------------------------------------------
// Build the header for the 1st sub-part, which will contain the SOAP envelope.
// It will look like this:

// Content-Type: application/xop+xml; charset=UTF-8; type="text/xml"
// Content-Transfer-Encoding: 8bit
// Content-ID: <rootpart@soapui.org>

rest.PartSelector = "1";
