 htmx also utilizes [response headers](https://htmx.org/docs/#response_headers) to affect client-side behavior. For each of these, this library provides `HttpHandler`s that can be chained along with the response. As an example, if the server returns a redirect response (301, 302, 303, 307), the `XMLHttpRequest` handler on the client will follow the redirection before htmx can do anything with it. To redirect to a new page, you would return an OK (200) response with an `HX-Redirect` header set in the response.
