Expected Behavior

A multipart/form-data http POST request is redirected to the desired endpoint.

Actual Behavior

An error 404 - not found http response is given.

Description

I won't include steps to reproduce the problem etc, because I'm pretty sure the feature is just not implemented (yet - or intentional).

Question

Is rerouting a file upload using multipart/form-data desired functionality, or is in an intentionally left out thing?
I could imagine you'd not want to reroute such a file upload because of the overhead - why not just upload the file directly to the API?
However, if the overhead is as little as the normal http requests are (about 1 ms), then I'd think it would be preferable to support multipart/form-data http post requests in reroutes.

Edit:
The reason I'm certain that I haven't just incorrectly configured the reroute, is as follows:
When I send the request with no file in the parameter, the reroute works and gets into my other API.
When I send the request with a file in the parameter, error 404 occurs, thrown by Ocelot presumably.
