 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

 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.

 Following Giraffe View Engine's lead, there are a set of attribute functions for htmx; for many of the attributes, there are also helper modules to assist with typing the values. The example below utilizes both:

 - `HxRequest` has a `Configure` function, which takes a list of strings; the other functions in the module allow for configuring the request.

-  HxRequest.Configure [ HxRequest.Timeout 500 ] |> _hxRequest

 - `HxTrigger` is _(by far)_ the most complex of these modules. Most uses won't need that complexity; however, complex triggers can be defined by piping into or composing with other functions. For example, to define an event that responds to a shift-click anywhere on the document, with a delay of 3 seconds before firing:
 
 ```fsharp
-  HxTrigger.Click
-  |> HxTrigger.Filter.Shift
-  |> HxTrigger.FromDocument
