 ## How to configure your hosting service to handle client-only routes
 
-Site hosting software and services need some help in order to serve client-only routes correctly. Most Gatsby pages have a corresponding html file that the server responds with when a user visits the page e.g. visiting `/blog/my-blog-post/` makes the server respond with `/blog/my-blog-post/index.html`. But client-only routes like `/app/why-gatsby-is-awesome/` don't have a corresponding html file. The server needs to be configured to know to serve instead `/app/index.html`.

 ### Self-hosting with NGINX and Apache
 
-Your server configuration should handle `GET` requests to `/app/*` e.g. `/app/why-gatsby-is-awesome` with `/app/index.html` and let the client handle the rendering of the route with the matching path. It is important to note that the response code should be a **200** (an OK) and not a **301** (a redirect). This can be done with NGINX using [`try_files`](https://docs.nginx.com/nginx/admin-guide/web-server/serving-static-content/#trying-several-options), or an [equivalent directive](https://serverfault.com/questions/290784/what-is-apaches-equivalent-of-nginxs-try-files) if using Apache.
