 > **Note**
-> `RequestBody` is basically a factory for request bodies. We cannot simply accept streams here, because a request body might have to be sent again on a redirect / retry. Additionally, `RequestBody` allows the body to set headers, which can be used to automatically set headers such as `Content-Type: application/json` for a `JsonBody`. Note that headers set via `RequestBody::getHeaders()` are only applied if the `Request` doesn't have such a header. This allows overriding the default body header in a request.
