Если же вы хотите добавить собственные заголовки, которые клиент сможет увидеть в браузере, то вам потребуется добавить их в настройки CORS ([CORS (Cross-Origin Resource Sharing)](cors.md){.internal-link target=_blank}), используя параметр `expose_headers`, см. документацию <a href="https://www.starlette.dev/middleware/#corsmiddleware" class="external-link" target="_blank">Starlette's CORS docs</a>....

Mas se você tiver cabeçalhos personalizados desejando que um cliente em um navegador esteja apto a ver, você precisa adicioná-los às suas configurações CORS ([CORS (Cross-Origin Resource Sharing)](cors.md){.internal-link target=_blank}) usando o parâmetro `expose_headers` documentado em <a href="https://www.starlette.dev/middleware/#corsmiddleware" class="external-link" target="_blank">Documentos CORS da Starlette</a>....
