Review comment:
In the description, it says the client needs to set `Content-Type`. However,
if content-type specified in the header via `-H` the request doesn't work. curl
man docs say how to specify content-type with the multipart upload.
```
You can also tell curl what Content-Type to use by using 'type=', in a
manner similar to:
curl -F "[email protected];type=text/html" url.com
```
After I've changed the example with `type=` it uploaded the jar.
