In general, ASGI middlewares are classes that expect to receive an ASGI app as the first argument.

So, in the documentation for third-party ASGI middlewares they will probably tell you to do something like:

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

        // Second operation (overwrite)
        data.putValue("key", "value2");
        assertEquals("value2", data.getValues("key")[0]);
        assertEquals(1, data.getValues("key").length);

        // Third operation with array (overwrite)
        data.putValues("key", new String[] { "value3", "value4", "value5" });
        assertEquals(3, data.getValues("key").length);
        assertEquals("value3", data.getValues("key")[0]);

      for (double first : ImmutableList.of(1.1, POSITIVE_INFINITY, NEGATIVE_INFINITY, NaN)) {
        values[0] = first;
        values[1] = -44.44;
        for (double third : ImmutableList.of(33.33, POSITIVE_INFINITY, NEGATIVE_INFINITY, NaN)) {
          values[2] = third;
          values[3] = 555.555;
          for (double fifth : ImmutableList.of(-2.2, POSITIVE_INFINITY, NEGATIVE_INFINITY, NaN)) {
            values[4] = fifth;
