CloudFlare CDN

cloudflare_cdn

When you are using CloudFlare, your site can no longer detect the visitor's IP address correctly, because all requests seem to originate from ClouFlare's IPs. This option is a fix for that. Navigate to OpenCart Admin Panel > Nitro > Settings > CDN > CloudFlare CDN. There is a single Enable / Disable switch. When enabled the client's real IP address will be detected based on the HTTP_CF_CONNECTING_IP header from CloudFlare. More information can be found here:
