Understanding Cloudflare Mobile Redirect

​​ Overview

Mobile Redirect allows you to automatically redirect mobile device visitors to a mobile-optimized website or subdomain home page. The redirect is done at the edge of Cloudflare’s network, improving the user experience by eliminating a roundtrip to your server.

You must have Cloudflare’s performance service enabled ( “orange clouded” in the DNS Settings) for the redirect to be active.

​​ Allow full site view

To allow your end users to view the full site on mobile, you’ll need to set the value of the following cookie on the root domain only to 0 (zero) at your origin server:

__cf_mob_redir = 0;

In this example, replace with your root domain.

To renew the mobile redirect, delete the cookie, or set it to expire after whatever duration you choose.
