In this example we use invented custom headers `X-Key` and `X-Token`.

But in real cases, when implementing security, you would get more benefits from using the integrated [Security utilities (the next chapter)](../security/index.md){.internal-link target=_blank}.

## Dependencies errors and return values

You can use the same dependency *functions* you use normally.

### Dependency requirements

von der auch die Sammlung Berggruen zahlreiche Porträts hier ausstellt, wird es 
möglich, ein tieferes Verständnis von Picassos Auffassung der Frau als Bild und  
Mensch  zu bekommen. Die Führung geht damit verbundenen Fragen im Kontext der 
Ausstellung nach. 
Folgendes Programm ist geplant:
15.45 Treffen (pünktlich!) im Museum Berggruen an der Kasse , Schloßstraße 1, 14059 Berlin.

    FluentIterable<Integer> cycle = fluent(1, 2).cycle();
    Iterator<Integer> iterator = cycle.iterator();
    iterator.next();
    iterator.remove();
    iterator.next();
    iterator.remove();
    assertFalse(iterator.hasNext());
    assertFalse(cycle.iterator().hasNext());
  }

  public void testAppend() {
    FluentIterable<Integer> result =

 * acquire(1000)} will result in exactly the same throttling, if any), but it affects the throttling
 * of the <i>next</i> request. I.e., if an expensive task arrives at an idle RateLimiter, it will be
 * granted immediately, but it is the <i>next</i> request that will experience extra throttling,
 * thus paying for the cost of the expensive task.

I'll show you some concrete examples in the next chapters.

Then the next concepts to consider are all about the program running your actual API (e.g. Uvicorn).

## Program and Process

	// A character used to truncate the object prefixes.
	// NOTE: only supported delimiter is '/'.
	Delimiter string

	// CommonPrefixes contains all (if there are any) keys between Prefix and the
	// next occurrence of the string specified by delimiter.
	CommonPrefixes []string

	EncodingType string // Not supported yet.
}

// TransitionedObject transitioned object tier and status.

          sum('pilot_total_xds_rejects', by=['type'])
        ),
        self.query(
          'Internal Errors',
          'pilot_total_xds_internal_errors'
        ),
        self.query(
          'Push Context Errors',
          'pilot_xds_push_context_errors'
        ),
      ],

      xdsConnections: [
        self.query(
          'Connections (client reported)',

## Integrated middlewares

**FastAPI** includes several middlewares for common use cases, we'll see next how to use them.

/// note | "Technical Details"

For the next examples, you could also use `from starlette.middleware.something import SomethingMiddleware`.

      StringBuilder sb = new StringBuilder();
      Iterator<String> iterator = components.iterator();
      if (iterator.hasNext()) {
        sb.append(iterator.next().toString());
        while (iterator.hasNext()) {
          sb.append(DELIMITER_STRING);
          sb.append(iterator.next());
        }
      }
      dummy ^= sb.toString().length();
    }
    return dummy;
  }
