Duplicate `Content-Type` header

In Postman duplicate headers are usually overridden i.e. This is a duplicate header and will be overridden by the Content-Type header added by you. except in the case below. How can I achieve this?

Hey @tafadzwagonera

You could just untick the auto-generated header and manually add 2 of the same header for the request.

I’ve used Content-Type here as an example and you can see from the Console, the request contained both headers.

I’m not sure of the endpoints you’re hitting so I don’t what behaviour is on the server-side if 2 of the same header are sent.

That makes two of us @dannydainton Postman console shows one header with multipart/related MIME getting sent to the server. I’m investigating an odd issue associated with the image I posted in the OP. Maybe I’ll have an answer by the close of the day.
