Redirects

CloudFlare have several redirection options:

Pages redirects

This blog uses CloudFlare Pages to host all its static content. To redirect old URLs to new ones, I use a _redirects file at the root of the repository. You should inspect that file to see how it works.

Note that this kind of redirects are not working at the domain-level. If you want to redirect https://example.com/ to https://www.example.com/, you need to use Page Rules.

Here are some of the most useful rules:

  • By default, pages are redirected for normalization:

    From

    To

    /contact

    /contact

    /contact/

    /contact

    /contact.html

    /contact

    /about

    /about/

    /about/

    /about/

    /about/index.html

    /about/

    Note how folder roots with an index.html are always redirected to an URL with a trailing slash, while HTML files are stripped of their extension.

    This behavior cannot be changed.

  • Redirect a single URL:

    /old-url /new-url 301

  • Redirect empty folders to the root of the site:

    /empty-folder      /   301
/empty-folder/     /   301

    I use this double rule to catch both the folder named empty-folder, and an hypothetical file named empty-folder.html. That way I am sure a parasitic empty-folder.html won’t be served.
