It's possible that `ORJSONResponse` might be a faster alternative.

### `RedirectResponse`

Returns an HTTP redirect. Uses a 307 status code (Temporary Redirect) by default.

You can return a `RedirectResponse` directly:

```Python hl_lines="2  9"

<p>
Not allowing a single write to write multiple values also means not using
the memory where a local variable will be written as temporary storage before the write.
For example, a compiler must not use <code>*p</code> as temporary storage in this program:
</p>

<pre>
*p = i + *p/2
</pre>

<p>
That is, it must not rewrite the program into this one:
</p>

<pre>
