Are MIME headers mandatory for a SOAP request?

Question

While building a SOAP request to be sent to a webservice, do I need to include MIME Headers or are they optional?

And do I need to specify the MIME type in the WSDL?

Answer 1

If you build your SOAP request from scratch by your own you have to set the MIME-Type.

The default MIME-Type for a SOAP request is

Content-Type: application/soap+xml; 

Also add the charset

charset=utf-8

There is no need to specify the MIME type in the WSDL. The content of a SOAP request is by default application/soap+xml.
