Send SOAP multipart/related with XML Body and Zip Attachment

See more REST Misc Examples

Demonstrates how to construct and send a multipart/related POST containing a SOAP XML body and a binary zip attachment. Go

    success := false

    // 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"
