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

    let rest = CkoRest()!

    // Connect to portal.mvp.bafin.de:444
    var bTls: Bool = true
    var port: Int = 444
    var bAutoReconnect: Bool = true
    var success: Bool = rest.connect("portal.mvp.bafin.de", port: port, tls: bTls, autoReconnect: bAutoReconnect)
    if success != true {
        print("\(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", value: "multipart/related; type=\"application/xop+xml\"; start=\"<rootpart@soapui.org>\"; start-info=\"text/xml\"")
    rest.addHeader("Content-Encoding", value: "gzip")

    rest.addHeader("MIME-Version", value: "1.0")
    rest.addHeader("Connection", value: "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"
    rest.addHeader("Content-Type", value: "application/xop+xml; charset=UTF-8; type=\"text/xml\"")
    rest.addHeader("Content-Transfer-Encoding", value: "8bit")
    rest.addHeader("Content-ID", value: "<rootpart@soapui.org>")
    soapXml.emitCompact = true
    soapXml.emitXmlDecl = false
    rest.setMultipartBodyString(soapXml.getXml())

    // Content-Type: application/octet-binary; name=A26MiFIR_Testfile_001.xml
    // Content-Transfer-Encoding: binary

    rest.setMultipartBodyString("<test>blah blah blah</test>")

    // The request is fully specified.  Now send the POST...

    // Turn on DebugMode.  This is a mode where no request is sent.  Instead, the request that would've been
    // sent is recorded and can be retrieved via the GetLastDebugRequest method.
    rest.debugMode = true

    var responseBody: String? = rest.fullRequestMultipart("POST", uriPath: "/services/ws/t_a26mifir")
    if rest.lastMethodSuccess != true {
