And also after the `response` is generated, before returning it.

For example, you could add a custom header `X-Process-Time` containing the time in seconds that it took to process the request and generate a response:

{* ../../docs_src/middleware/tutorial001.py hl[10,12:13] *}

/// tip

  fun get() {
    val executor = Executors.newCachedThreadPool()

    val completableFuture = execute(engine, executor, "https://google.com/robots.txt")

    try {
      val response = completableFuture.get(10, TimeUnit.SECONDS)

      assertEquals(200, response.code)
      assertEquals("h3", response.negotiatedProtocol)
      assertTrue(response.content.contains("Disallow"))
    } catch (ee: ExecutionException) {

		time.Sleep(time.Second)
	}
	rx := float64(globalNetPerfRX.RXSample)
	delta := globalNetPerfRX.firstToDisconnect.Sub(globalNetPerfRX.lastToConnect)
	if delta < 0 {
		rx = 0
		errStr = "network disconnection issues detected"
	}

	globalNetPerfRX.Reset()
	return madmin.NetperfNodeResult{Endpoint: "", TX: r.n / uint64(duration.Seconds()), RX: uint64(rx / delta.Seconds()), Error: errStr}
}

* `expose_headers` - Indicate any response headers that should be made accessible to the browser. Defaults to `[]`.
* `max_age` - Sets a maximum time in seconds for browsers to cache CORS responses. Defaults to `600`.

The middleware responds to two particular types of HTTP request...

### CORS preflight requests { #cors-preflight-requests }
