 *  New: Update to h2-14 and hpack-9.
 *  New: OkHttp includes a user-agent by default, like `okhttp/2.1.0-RC1`.
 *  Fix: Handle response code `308 Permanent Redirect`.
 *  Fix: Don't skip the callback if a call is canceled.
 *  Fix: Permit hostnames with underscores.
 *  Fix: Permit overriding the content-type in `OkApacheClient`.
 *  Fix: Use the socket factory for direct connections.

### Understand that Code { #understand-that-code }

The important point is just using **`AfterValidator` with a function inside `Annotated`**. Feel free to skip this part. 🤸

But if you're curious about this specific code example and you're still entertained, here are some extra details.

#### String with `value.startswith()` { #string-with-value-startswith }

In this case, you can disable the response model generation by setting `response_model=None`:

{* ../../docs_src/response_model/tutorial003_05_py310.py hl[7] *}

This will make FastAPI skip the response model generation and that way you can have any return type annotations you need without it affecting your FastAPI application. 🤓
