By default, **FastAPI** would automatically convert that return value to JSON using the `jsonable_encoder` explained in [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

Then, behind the scenes, it would put that JSON-compatible data (e.g. a `dict`) inside of a `JSONResponse` that would be used to send the response to the client.

	if i.User != nil {
		u := *i.User
		out.User = &u
	}
	return &out
}

// Modify the request to handle the target URL
func (f *Forwarder) modifyRequest(outReq *http.Request, target *url.URL) {
	outReq.URL = copyURL(outReq.URL)
	outReq.URL.Scheme = target.Scheme
	outReq.URL.Host = target.Host

	u := f.getURLFromRequest(outReq)

	outReq.URL.Path = u.Path
	outReq.URL.RawPath = u.RawPath
