There may be many routes for a single address. For example, a webserver that is hosted in multiple datacenters may yield multiple IP addresses in its DNS response.

In limited situations OkHttp will retry a route if connecting fails:

## Getting Started

There are 2 ways to try Fess. The first is to download and install yourself. The second is to use [Docker](https://www.docker.com/products/docker-engine).

By this point, it's already clear that **FastAPI** with its ideas is being useful for many people.

It is being chosen over previous alternatives for suiting many use cases better.

Many developers and teams already depend on **FastAPI** for their projects (including me and my team).

But still, there are many improvements and features to come.

The drives should all be of approximately the same size.

   * note that listeners added after this point may be executed before those previously added, and
   * note that the execution order of all listeners is ultimately chosen by the implementations of
   * the supplied executors.

   * <p>This method is idempotent. Calling it several times in parallel is semantically equivalent
   * to calling it exactly once.

certificar de que é um único processo executando essas etapas anteriores *mesmo* se depois, você iniciar **vários processos** (vários trabalhadores) para o próprio aplicativo. Se essas etapas fossem executadas por **vários processos**, eles **duplicariam** o trabalho executando-o em **paralelo**, e se as etapas fossem algo delicado como uma migração de banco de dados, elas poderiam causar conflitos entre si.

Claro, há alguns casos em que não há problema em executar as etapas anteriores várias...

Upgrading to OkHttp 4
=====================

OkHttp 4.x upgrades our implementation language from Java to Kotlin and keeps everything else the
same. We’ve chosen Kotlin because it gives us powerful new capabilities while integrating closely
with Java.

We spent a lot of time and energy on retaining strict compatibility with OkHttp 3.x. We’re even
keeping the package name the same: `okhttp3`!

There are three kinds of compatibility we’re tracking:

Dasselbe Beispiel würde dann so aussehen:

{* ../../docs_src/dependencies/tutorial004_an_py310.py hl[19] *}

... und **FastAPI** wird wissen, was zu tun ist.

Wenn Sie das eher verwirrt, als Ihnen zu helfen, ignorieren Sie es, Sie *brauchen* es nicht.

Diese zusätzlichen Responses werden in das OpenAPI-Schema aufgenommen, sodass sie auch in der API-Dokumentation erscheinen.

Für diese zusätzlichen Responses müssen Sie jedoch sicherstellen, dass Sie eine `Response`, wie etwa `JSONResponse`, direkt zurückgeben, mit Ihrem Statuscode und Inhalt.

   * <p>We have chosen this approach over at least two alternatives:
   *
   * <ul>
   *   <li>We could change the serialization of this class incompatibly. We have reserved the right
   *       to make such changes to our serialized forms, and we have made them before, usually
   *       without trouble. In this case, my guess is that our chosen approach is even less likely
