// 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"');
