* higher value than you need can waste space and time, and a significantly lower value can lead
   * to thread contention. But overestimates and underestimates within an order of magnitude do not
   * usually have much noticeable impact. A value of one permits only one thread to modify the map
   * at a time, but since read operations can proceed concurrently, this still yields higher

    * `bearer`: заголовок `Authorization` со значением `Bearer {уникальный токен}`. Это унаследовано от OAuth2.
    * Базовая аутентификация по протоколу HTTP.
    * HTTP Digest и т.д.
* `oauth2`: все способы обеспечения безопасности OAuth2 называемые "потоки" (англ. "flows").

* `compresslevel` - Used during GZip compression. It is an integer ranging from 1 to 9. Defaults to `9`. Lower value results in faster compression but larger file sizes, while higher value results in slower compression but smaller file sizes.

## Other middlewares { #other-middlewares }

There are many other ASGI middlewares.

For example:

  * Una cookie.
* `http`: sistemas de autenticación HTTP estándar, incluyendo:
  * `bearer`: un header `Authorization` con un valor de `Bearer ` más un token. Esto se hereda de OAuth2.
  * Autenticación básica HTTP.
  * Digest HTTP, etc.
* `oauth2`: todas las formas de OAuth2 para manejar la seguridad (llamadas "flujos").

### DurationSeconds

The duration, in seconds. The value can range from 900 seconds (15 minutes) up to 365 days. If value is higher than this setting, then operation fails. By default, the value is set to 3600 seconds.
