CloudCannon serves a 404 page when it can’t find a file on your site. Create your own 404 page to blend in with the rest of your site.

To create a custom 404 page:

  1. Create a file called 404.html at the root of your site
  2. Add the content you want CloudCannon to serve

Set the permalink of your page to /404.html if you are using Jekyll and non-default permalinks.

To use different 404 pages for parts of your site, you can use the 404 status code in a routing.json file.

For example, if we want a unique 404 page for blog posts, we might add a /404-blog.html page on our site. Your routing file can then be configured to use this:

  "routes": [
      "from": "/blog/.*",
      "to": "/404-blog.html",
      "status": 404,
      "forced": false

A 404 routing status will transparently proxy the original request. The URL will not change, and the contents of /404-blog.html will be returned.

Make sure to set forced: false, otherwise all requests that match the from regex will return a 404, regardless of whether the requested file exists.
