Cloudflare accept `.html` at end of URLs

Question

I moved a static website, built with 11ty, from AWS to Cloudflare pages. I am having a problem: Cloudflare is not handling .html at the end of URLs the same way that AWS was.

So, for example --

• This link works: https://johnskinnerportfolio.com/blog/ruby_330_error/
• This one does not: https://johnskinnerportfolio.com/blog/ruby_330_error.html

The second link with the HTML extension is broken. This is a problem because there are a lot of outstanding links which have .html at the end.

Is there some configuration detail in Cloudflare, or in Eleventy, which can restore these URLs to a working state?

Answer 1

To answer my own question, the solution was to create a file named _redirects (with no file extension) in the root folder of my project containing:

/*.html /:splat 301 

This redirects people to the working URLs, per the documentation
