+htmx can use to update different parts of the page, which is called [Out Of Band Swaps](https://htmx.org/docs/#oob_swaps). Spring offers the ability to return

-An `HtmxView` can be formed from view names, as above, or fully resolved `View` instances, if the controller knows how
-to do that, or from `ModelAndView` instances (resolved or unresolved). Each fragment can have its own model, which is merged with the controller model before rendering.

 ### Exceptions
 
 It is also possible to use `HtmxRequest` and `HtmxResponse` as method argument in handler methods annotated with `@ExceptionHandler`.
