I had to run this site on til.simonwillison.org for 24 hours due to a domain registration mistake I made.

Once I got til.simonwillison.net working again I wanted to permanently redirect the URLs on the temporary site to their equivalent on the correct domain.

Since I was running the site behind Cloudflare, I could get Cloudflare to handle the redirects for me using a Page Rule, which support wildcards for redirects.

I used these settings:

  • URL: til.simonwillison.org/*
  • Setting: Forwarding URL
  • Status code: 301 (permanent redirect)
  • Destination URL: https://til.simonwillison.net/$1

This did the right thing - hits to e.g. https://til.simonwillison.org/cloudflare?a=1 redirect to https://til.simonwillison.net/cloudflare?a=1

Here's a screenshot of the settings page I used to create the new Page Rule:

Screenshot of the Cloudflare interface. Create a Page Rule for simonwillison.org. If the URL matches: URL (required) til.simonwillison.org/* Then the settings are: Forwarding URL https://til.simonwillison.net/$1 Select status code (required) 301 - Permanent Redirect. Save and Deploy Page Rule
