Translate MIME to HTTP Form Assertion

The Translate MIME to HTTP Form assertion allows you to parse and convert an incoming multi-part MIME message into an HTTP form submission such as would be submitted by a browser-like client. The Gateway converts incoming MIME content to HTTP form format in accordance with an ordered list of configured field names. If an incoming message does not contain sufficient MIME parts for the field names configured for conversion in the Translate MIME to HTTP Form assertion, then the assertion will fail.
