The same way, you can define logic (code) that should be executed when the application is **shutting down**. In this case, this code will be executed **once**, **after** having handled possibly **many requests**.

requests_max                    (number)    set the maximum number of concurrent requests (default: 'auto')
cluster_deadline                (duration)  set the deadline for cluster readiness check (default: '10s')
cors_allow_origin               (csv)       set comma separated list of origins allowed for CORS requests (default: '*')

### Request metrics

Metrics about requests served by the current node.

| Path            | Description                                   |
|-----------------|-----------------------------------------------|
| `/api/requests` | Metrics over all requests.                    |
| `/bucket/api`   | Metrics over all requests for a given bucket. |

#### `/api/requests`

        // When
        Smb2CancelRequest request = new Smb2CancelRequest(mockConfig, mid, asyncId);
        request.setRequestCredits(credits);
        request.setTid(treeId);

        // Then
        assertEquals(mid, request.getMid(), "MID should be set correctly");
        assertEquals(asyncId, request.getAsyncId(), "AsyncId should be set correctly");
        assertEquals(credits, request.getCredit(), "Credits should be set correctly");

        return bytesReceived.get();
    }

    /**
     * Get number of requests sent
     *
     * @return requests sent
     */
    public long getRequestsSent() {

/// note | Technical Details

You could also use `from starlette.requests import Request`.

**FastAPI** provides it directly just as a convenience for you, the developer. But it comes directly from Starlette.

Here we use it to create a `GzipRequest` from the original request.

/// note | Technical Details

A `Request` has a `request.scope` attribute, that's just a Python `dict` containing the metadata related to the request.

 * that controls the interval between requests to the same host.
 * It uses a ConcurrentMap to store the last access time for each host.
 * The delayBeforeProcessing method is overridden to introduce a delay before processing a URL,
 * ensuring that requests to the same host are not made too frequently.

    /**
     * Map of pending requests to their corresponding responses.

    protected HashMap response_map = new HashMap(4);
