## Adicione headers customizados

Há certas situações em que é bastante útil poder adicionar headers customizados no HTTP error. Exemplo disso seria adicionar headers customizados para tipos de segurança.

Você provavelmente não precisará utilizar esses headers diretamente no seu código.

Mas caso você precise, para um cenário mais complexo, você pode adicionar headers customizados:

```Python hl_lines="14"

            }

            data.setContent(EntityUtils.toString(response.getEntity(), Charsets.UTF_8));
            final Header[] headers = response.getAllHeaders();
            for (final Header header : headers) {
                data.putValue(header.getName(), header.getValue());
            }
        } catch (final IOException e) {
            throw new ExtractException(e);
        } finally {

    Serialization.getFieldSetter(TreeMultiset.class, "rootReference")
        .set(this, new Reference<AvlNode<E>>());
    AvlNode<E> header = new AvlNode<>();
    Serialization.getFieldSetter(TreeMultiset.class, "header").set(this, header);
    successor(header, header);
    Serialization.populateMultiset(this, stream);
  }

[`net/http.ServeContent`](/pkg/net/http#ServeContent),
[`net/http.ServeFile`](/pkg/net/http#ServeFile), and
[`net/http.ServeFS`](/pkg/net/http#ServeFS) to
remove Cache-Control, Content-Encoding, Etag, and Last-Modified headers
when serving an error. This behavior is controlled by
the [`httpservecontentkeepheaders` setting](/pkg/net/http#ServeContent).
Using `httpservecontentkeepheaders=1` restores the pre-Go 1.23 behavior.
