# Silverback CDN Redirect

To be used with static websites, hosted on a CDN (e.g. Gatsby and Netlify).

Solves two problems:

1. Can resolve redirects that are not stored in CDN config, which is necessary,

   since Drupal's redirect module creates a redirect for each path change, which

   can be a lot. In that case, the redirect is resolved by rewriting the request

   to Drupal.

2. Rewrite paths not know by the CDN, to client-side rendered pages. Useful for

   pages that should not be rendered statically.

## Flowchart!

  subgraph Drupal

      RedirectCheck{Drupal redirect exists?}

      EntityCheck{Drupal page exists?}

      RequestNotFound[Fetch 404 from CDN]

      RequestCSR[Fetch CSR template from CDN]

  end

  subgraph CDN

      Request(User navigates to path)

      CDNCheck{Static page exists?}

      CDNDeliver{{Respond with static page}}

      CDNRedirect{{Respond with redirect from Drupal}}

      CDNRewrite{{Respond with content from Drupal}}

  end

  CDNCheck -- no --> RedirectCheck

  RedirectCheck -- yes --> CDNRedirect

  RedirectCheck -- no --> EntityCheck

  Request --> CDNCheck

  CDNCheck -- yes --> CDNDeliver

  EntityCheck -- no --> RequestNotFound

  EntityCheck -- yes --> RequestCSR

  RequestNotFound ----> CDNRewrite

  RequestCSR ----> CDNRewrite

```

## Drupal config

- Patch Drupal with a patch from

  [#2741939](https://www.drupal.org/project/drupal/issues/2741939)

- Enable the module

- Set the settings, for example:

  ```

  drush cset silverback_cdn_redirect.settings base_url https://my-gatsby.site

  drush cset silverback_cdn_redirect.settings 404_path /404

  drush cset silverback_cdn_redirect.settings should_prefix_404_path true

  ```

## Gatsby config

- Add

  [gatsby-plugin-netlify](https://www.gatsbyjs.com/plugins/gatsby-plugin-netlify)

  package

- Configure the catch-all redirect in `createPages`

  ```js

  createRedirect({

    fromPath: '/*',

    toPath: `https://my-drupal.site/cdn-redirect/:splat`,

    statusCode: 200,

  });

  ```

  Note: `statusCode: 200` is required to "hide" the request to backend from the

  browser.
