A server may want to respond to a request that originated from htmx differently than a regular request.

In this case, the developer can provide a partial layout to be used for these responses, while returning the full page for regular requests. The `IsHtmx` property makes this easy...
```fsharp ```fsharp
// "partial" and "full" are handlers that return the contents; // "partial" and "full" are handlers that return the contents;
// "view" can be whatever your view engine needs for the body of the page // "view" can be whatever your view engine needs for the body of the page

``` ```
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. htmx also utilizes [response headers](https://htmx.org/docs/#response_headers) to affect client-side behavior.

Some attributes have known values, such as `hx-trigger` and `hx-swap`; for these, there are modules with those values. For example, `HxTrigger.Load` could be used in the example above, to ensure that the known values are spelled correctly. `hx-trigger` can also take modifiers, such as an action that only responds to `Ctrl`+click.
