You can add code to be run with the `request`,  before any *path operation* receives it.

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:

```Python hl_lines="10  12-13"
{!../../docs_src/middleware/tutorial001.py!}
```

    if (requestHeaderLength != null) {
      val responseHeadersEnd = listener.removeUpToEvent<RequestHeadersEnd>()
      MatcherAssert.assertThat(
        "request header length",
        responseHeadersEnd.headerLength,
        requestHeaderLength,
      )
    } else {
      assertThat(listener.recordedEventTypes())
        .doesNotContain("RequestHeadersEnd")
    }

		w.Header().Set("Content-Type", string(contentType))
