Using `check_same_thread=False` allows FastAPI to use the same SQLite database in different threads. This is necessary as **one single request** could use **more than one thread** (for example in dependencies).

Don't worry, with the way the code is structured, we'll make sure we use **a single SQLModel *session* per request** later, this is actually what the `check_same_thread` is trying to achieve.

## Recap { #recap }

Declare headers with `Header`, using the same common pattern as `Query`, `Path` and `Cookie`.

    int h1 = Objects.hashCode(1, "two", 3.0);
    int h2 = Objects.hashCode(Integer.valueOf(1), new String("two"), Double.valueOf(3.0));
    // repeatable
    assertEquals(h1, h2);

    // These don't strictly need to be true, but they're nice properties.
    assertTrue(Objects.hashCode(1, 2, null) != Objects.hashCode(1, 2));
    assertTrue(Objects.hashCode(1, 2, null) != Objects.hashCode(1, null, 2));

        assertThrows(VerifyException.class, () -> verifyNotNull(null, FORMAT, 5));
    checkMessage(expected);
  }

  @J2ktIncompatible
  @GwtIncompatible // NullPointerTester
  public void testNullPointers() {
    // Don't bother testing: Verify is like Preconditions. See the discussion on that class.
  }

  private static final Object IGNORE_ME =
      new Object() {
        @Override
        public String toString() {

```

The good news is, in most cases, you will be able to simply use `|` to define unions of types:

```python
def say_hi(name: str | None):
    print(f"Hey {name}!")
```

### Choosing between application and network interceptors

Each interceptor chain has relative merits.

**Application interceptors**

 * Don't need to worry about intermediate responses like redirects and retries.
 * Are always invoked once, even if the HTTP response is served from the cache.

        .receivedResponseAtMillis(System.currentTimeMillis())
        .build()
        .also {
          chain.eventListener.satisfactionFailure(call, it)
        }
    }

    // If we don't need the network, we're done.
    if (networkRequest == null) {
      return cacheResponse!!
        .newBuilder()
        .cacheResponse(cacheResponse.stripBody())
        .build()
        .also {
