# Response Headers { #response-headers }

## Use a `Response` parameter { #use-a-response-parameter }

You can declare a parameter of type `Response` in your *path operation function* (as you can do for cookies).

And then you can set headers in that *temporal* response object.

{* ../../docs_src/response_headers/tutorial002_py310.py hl[1, 7:8] *}

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

/// warning | Uyarı

Bir *path operation* içinde birden fazla `Form` parametresi tanımlayabilirsiniz, ancak JSON olarak almayı beklediğiniz `Body` alanlarını da ayrıca tanımlayamazsınız; çünkü bu durumda request'in body'si `application/x-www-form-urlencoded` ile encode edilmiş olur.

/// warning

You can declare multiple `Form` parameters in a *path operation*, but you can't also declare `Body` fields that you expect to receive as JSON, as the request will have the body encoded using `application/x-www-form-urlencoded` instead of `application/json`.
