1. This is the generator function. It's a "generator function" because it contains `yield` statements inside.
2. By using a `with` block, we make sure that the file-like object is closed after the generator function is done. So, after it finishes sending the response.

 *  **Call canceling is more reliable.**  We had a bug where a socket being
     connected wasn't being closed when the application used `Call.cancel()`.

 *  **Changing a HttpUrl’s scheme now tracks the default port.** We had a bug
    where changing a URL from `http` to `https` would leave it on port 80.
