Hugo site for frobiovox.com, hosted on AWS S3 behind Cloudflare.

To redirect legacy .html URLs (from the old Jekyll site) to the canonical trailing-slash URLs generated by Hugo, add a single redirect rule in the Cloudflare dashboard.

1. Log in to the Cloudflare dashboard and select the frobiovox.com zone.
2. Go to Rules → Redirect Rules.
3. Click Create rule.
4. Set the rule name to something like Legacy .html redirect.
5. Under If incoming requests match, choose Wildcard pattern and enter:

   www.frobiovox.com/*.html
   

6. Under Then, set the action to Dynamic redirect with:
   • Expression: concat("https://www.frobiovox.com/", wildcard_replace(http.request.uri.path, "/*.html", "${1}"), "/")
   • Status code: 301
7. Save and deploy the rule.

After the rule is active, a request to:

https://www.frobiovox.com/posts/2013/10/06/support-should-not-be-based-on-marketshare.html

will redirect to:
