Sets HTTP response in multipart mode of given type. Calling one of the standard request methods will send the HTTP response as the given multipart type, even if no other part has been set.

The root HTTP part must be handled via the standard HTTPServiceRequest methods such as sendTextRequest(), sendXmlRequest(), sendDataRequest() and BeginXmlResponse().

In case of error, the method throws an exception and sets the STATUS variable. Depending on the error, a human-readable description of the problem is available in the SQLCA.SQLERRM register. See Error handling in GWS calls (STATUS).
