-By default, SvelteKit will render (or [prerender](glossary#Prerendering)) any component first on the server and send it to the client as HTML. It will then render the component again in the browser to make it interactive in a process called [**hydration**](glossary#Hydration). For this reason, you need to ensure that components can run in both places. SvelteKit will then initialize a [**router**](routing) that takes over subsequent navigations.
+By default, SvelteKit will render (or [prerender](glossary#Prerendering)) any component first on the server and send it to the client as HTML. It will then render the component again in the browser to make it interactive in a process called [_hydration_](glossary#Hydration). For this reason, you need to ensure that components can run in both places. SvelteKit will then initialize a [_router_](routing) that takes over subsequent navigations.
 
 You can control each of these on a page-by-page basis by exporting options from [`+page.js`](routing#page-page.js) or [`+page.server.js`](routing#page-page.server.js), or for groups of pages using a shared [`+layout.js`](routing#layout-layout.js) or [`+layout.server.js`](routing#layout-layout.server.js). To define an option for the whole app, export it from the root layout. Child layouts and pages override values set in parent layouts, so — for example — you can enable prerendering for your entire app then disable it for pages that need to be dynamically rendered.

+This function allows you to modify (or replace) the result of an [`event.fetch`](load#Making-fetch-requests) call that runs on the server (or during prerendering) inside an endpoint, `load`, `action`, `handle`, `handleError` or `reroute`.
 
 For example, your `load` function might make a request to a public URL like `https://api.yourapp.com` when the user performs a client-side navigation to the respective page, but during SSR it might make sense to hit the API directly (bypassing whatever proxies and load balancers sit between it and the public internet).

-**Credentials**
+Requests made with `event.fetch` follow the browser's credentials model — for same-origin requests, `cookie` and `authorization` headers are forwarded unless the `credentials` option is set to `"omit"`. For cross-origin requests, `cookie` will be included if the request URL belongs to a subdomain of the app — for example if your app is on `my-domain.com`, and your API is on `api.my-domain.com`, cookies will be included in the request.

 One of the more interesting features of Yarn Berry is the ability to have a single global cache for packages, instead of having multiple copies for each project on the disk. However, setting `enableGlobalCache` to true causes building to fail, so it is recommended to add the following to the `.yarnrc.yml` file:
