 The following methods are provided:
 
-##### `app.render(request: Request, options?: RenderOptions)`
+##### `app.render(request, { routeData, locals })`
 
 This method calls the Astro page that matches the request, renders it, and returns a Promise to a [Response](https://developer.mozilla.org/en-US/docs/Web/API/Response) object. This also works for API routes that do not render pages.
 
 ```js
 const response = await app.render(request);
 ```
 
-##### `RenderOptions`
+The method accepts a mandatory `request` argument, and an optional argument for [`routeData`](/en/reference/integrations-reference/#routedata-type-reference) and [`locals`](/en/reference/api-reference/#astrolocals).
 
-The `app.render()` method accepts a mandatory `request` argument, and an optional `RenderOptions` object for [`addCookieHeader`](#addcookieheader), [`clientAddress`](#clientaddress), [`locals`](#locals), and [`routeData`](#routedata).
-
-###### `addCookieHeader`
-
-Whether or not to automatically add all cookies written by `Astro.cookie.set()` to the response headers.
-
-When set to `true`, they will be added to the `Set-Cookie` header of the response as comma separated key-value pairs. You can use the standard `response.headers.getSetCookie()` API to read them individually.
-When set to `false`(default), the cookies will only be available from `App.getSetCookieFromResponse(response)`.
-
-```js
-const response = await app.render(request, { addCookieHeader: true });
-```
-
-###### `clientAddress`
-
-The client IP address that will be made available as [`Astro.clientAddress`](/en/reference/api-reference/#astroclientaddress) in pages, and as `ctx.clientAddress` in API routes and middleware.
-
-The example below reads the `x-forwarded-for` header and passes it as `clientAddress`. This value becomes available to the user as `Astro.clientAddress`.
-
-```js "clientAddress"
-const clientAddress = request.headers.get("x-forwarded-for");
-const response = await app.render(request, { clientAddress });
-```
-
-###### `locals`
-
-The [`context.locals` object](/en/reference/api-reference/#contextlocals) used to store and access information during the lifecycle of a request.
+Provide a value for `routeData` if you already know the route to render. Doing so will bypass the internal call to [`app.match`](#appmatchrequest) to determine the route to render.
 
 The example below reads a header named `x-private-header`, attempts to parse it as an object and pass it to `locals`, which can then be passed to any [middleware function](/en/guides/middleware/).
 
-```js "locals"

 const privateHeader = request.headers.get("x-private-header");

 ##### `app.match(request)`
 
 This method is used to determine if a request is matched by the Astro app's routing rules.
