A server may want to respond to a request that originated from htmx differently than a regular request. One way htmx can provide the same feel as a Single Page Application (SPA) is by swapping out the `body` content (or an element within it) instead of reloading the entire page. 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
// "partial" and "full" are handlers that return the contents;
// "view" can be whatever your view engine needs for the body of the page
let result view : HttpHandler =
// "partial" and "full" are handlers that return the contents;
// "view" can be whatever your view engine needs for the body of the page
let result view : HttpHandler =
fun next ctx ->
match ctx.Request.IsHtmx && not ctx.Request.IsHtmxRefresh with
| true -> partial view
| false -> full view
if ctx.Request.IsHtmx && not ctx.Request.IsHtmxRefresh then
partial view
else
full view
```
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.
```fsharp
let theHandler : HttpHandler =
let theHandler : HttpHandler =
fun next ctx ->
// some interesting stuff
withHxRedirect "/the-new-url" >=> Successful.OK
// some interesting stuff
withHxRedirect "/the-new-url" >=> Successful.OK
```
Of note is that the `HX-Trigger` headers can take either one or more events. For a single event with no parameters, use `withHxTrigger`; for a single event with parameters, or multiple events, use `withHxTriggerMany`. Both these have `AfterSettle` and `AfterSwap` versions as well.

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. The `HxTrigger` module has a `Filter` submodule to assist with defining these actions.
```fsharp
let shiftClick =
let shiftClick =
p [ _hxGet = "/something"; _hxTrigger (HxTrigger.Filter.Shift HxTrigger.Click) ] [
str "hold down Shift and click me"
]
str "hold down Shift and click me"
]
```
If you want to load htmx from unpkg, `Htmx.Script.minified` or `Htmx.Script.unminified` can be used to load the script in your HTML trees.
