Pero si tienes headers personalizados que quieres que un cliente en un navegador pueda ver, necesitas agregarlos a tus configuraciones de CORS (leer más en [CORS (Cross-Origin Resource Sharing)](../tutorial/cors.md)), usando el parámetro `expose_headers` documentado en [la documentación CORS de Starlette](https://www.starlette.dev/middleware/#corsmiddleware)....

Но если у вас есть пользовательские заголовки, которые вы хотите показывать клиенту в браузере, вам нужно добавить их в настройки CORS (подробнее см. в [CORS (Cross-Origin Resource Sharing)](../tutorial/cors.md)), используя параметр `expose_headers`, описанный в [документации Starlette по CORS](https://www.starlette.dev/middleware/#corsmiddleware)....

            path = path.substring(0, path.length() - 1);
        }

        return path;

blocking APIs. Each application-layer thread wants to do blocking I/O for a specific stream, but the streams are multiplexed on the socket. You can't just talk to the socket, you need to cooperate with the other application-layer threads that you're sharing it with.

Framing rules make it impractical to implement http/2 correctly on a single blocking thread. The flow-control features introduce feedback between reads and writes, requiring writes to acknowledge reads and reads to throttle writes....
