Support for multipart/form-data Content-Type in HTTP response

[vmaffione]

Hi,
As far as I can see support for multipart/form-data is only available for HTTP requests (both for the client and server side).

Any opinion/plans about adding client and server support also for HTTP responses? This would be handy for all those cases where a HTTP server needs to "atomically" return one or more files (application/octet-stream) along with associated metadata (e.g. JSON, XML), without resorting to encoding the files, e.g. as BASE64 within a JSON field, since this latter solution bloats the response and adds considerable processing and memory overhead...

Thanks

@vmaffione thanks for the feature request. I don't have time to implement it for now, but I keep it with the 'enhancement' label.

Sure, but so do you think it would make sense to implement something like this?
I am still not sure the HTTP standard allows to use such a content-type within a response...

I haven't investigated if it's possible to implement the feature, yet. Do you know any HTTP libraries which support such a feature? If so, I'll take a look at how those libraries implement it. I personally don't need it on my projects at this point though.

To be honest, I only found this stack overflow discussion
https://stackoverflow.com/questions/47067312/multipart-http-response
mentioning that it is possible to achieve that with Node.js
