Redirect Loops Settings

SSL with CloudFlare and Really Simple SSL

If you are a CloudFlare user, there are a few things to consider when migrating to SSL. If you run into redirect loops when you use CloudFlare, and have activated Really Simple SSL, check if you have configured below settings correctly.

Page rules

In CloudFlare you have the option to define page rules. If this page rule redirects all requests to http, activating Really Simple SSL will result in CloudFlare forcing your site to http, and Really Simple SSL forcing your site to https. A redirect loop is the result. You can remove the page rule, or change it into a page rule to https.

SSL settings in CloudFlare

If you have your own certificate, you should select Full SSL. If you use the CloudFlare SSL option, choose flexible SSL. Not selecting the correct option might cause redirect loops.

Make sure CloudFlare does not cache old data

When we migrate a CloudFlare website to SSL, we always start with turn development mode in CloudFlare on. When everything is ready, purge the cache, then turn off development mode.

If you have not purged CloudFlare cache, you might get mixed content on your site.

If you run into anything that is not covered here, please let me know!

    I had a redirect loop problem using Really Simple SSL and Cloudflare. I disabled both Enable WordPress 301 redirection to SSL and Enable 301 .htaccess redirect,

    I set SSL to Full at Cloudflare and it works,

    I’m not sure if I should enable these options again or Cloudflare will take care of it?

    What’s your advice?

      Hi Oxana,

      it looks like your set-up is fine. When using your own SSL certificate, Cloudflare SSL should be set to full. We recommend to use the .htaccess redirect since it’s the fastest. Your site seems to work fine at the moment so I wouldn’t change anything.
