/**
 * Service for detecting and providing information about the operating system (OS)

 * <p>
 * This service provides a platform-independent way to:
 * <ul>
 * <li>Query basic OS information like name, architecture, and version</li>
 * <li>Determine the OS family (e.g., Windows, Unix, Mac)</li>
 * <li>Check if the current OS is Windows-based</li>

## Executando na inicialização { #running-on-startup }

Na maioria dos casos, quando você cria uma API web, você quer que ela esteja **sempre em execução**, ininterrupta, para que seus clientes possam sempre acessá-la. Isso é claro, a menos que você tenha um motivo específico para querer que ela seja executada somente em certas situações, mas na maioria das vezes você quer que ela esteja constantemente em execução e **disponível**.

# Dependencias Globales { #global-dependencies }

Para algunos tipos de aplicaciones, podrías querer agregar dependencias a toda la aplicación.

Similar a como puedes [agregar `dependencies` a los *path operation decorators*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, puedes agregarlos a la aplicación de `FastAPI`.

En ese caso, se aplicarán a todas las *path operations* en la aplicación:

        assertEquals(1, response.getNum());
        assertEquals("全文 検索", response.getWords().get(0));

        response = suggester.suggest().addKind("query").execute().getResponse();
        assertEquals(1, response.getNum());

        SuggestResponse response2 = suggester.suggest().setSuggestDetail(true).execute().getResponse();
        assertEquals(2, response2.getNum());

As recommended by the HTTP RFC the max age of a document is defaulted to 10% of the 
document's age at the time it was served based on "Last-Modified". Default expiration dates aren't used for URIs 
containing a query.

### Cache Miss

Under a cache miss the normal request events are seen but an additional event shows the presence of the cache.

        assertEquals("server", hostOnlyUrl.getHost());
        assertEquals(445, hostOnlyUrl.getPort());
        assertEquals("", hostOnlyUrl.getPath());

        // Test SMB URL with query parameters
        URL queryUrl = new URL(null, "smb://host/share?param=value", handler);
        assertEquals("smb", queryUrl.getProtocol());
        assertEquals("host", queryUrl.getHost());
