About Cloudflare

Cloudflare protects your websites from online threats and DDoS attacks, while making them twice as fast around the world. Cloudflare runs a globally distributed network. Once you enable Cloudflare on your website, the traffic routes through the Cloudflare network before it reaches your server. Cloudflare stops malicious web traffic, fights DDoS attacks and automatically caches and delivers content for faster load times.

Cloudflare ServerShield only accelerates and protects domains that have CNAME (canonical name) records - specifically, the www subdomain (for example,www.example.com ). The root domain (example.com ) uses an A record and cannot be routed directly through the Cloudflare network. Therefore, to make sure Cloudflare handles all traffic to your site, you should forward root domain requests to the www subdomain.

Tip

For information about how to configure the WordPress URL so it includes the www subdomain, please see this article.

Configuring Cloudflare ServerShield

Once you have activated Cloudflare, you can access several configuration options by clicking the Manage Cloudflare link at the that appears to the right of the On / Off switch. Available configurations include:

• Purge Cache Click the Purge Cache button to immediately purge cached resources for your website. This is useful to see your changes immediately after updating your website.

• Security Level Select the security level from the list box. Adjust the basic security level to modify Cloudflare's protection behavior. The Security Level uses the IP reputation of a visitor to decide whether to present a challenge. Visitors with high reputation IP addresses will go directly to the site while visitors from lower reputation IP addresses may need to complete a CAPTCHA before viewing the site.

• Always Online Select On or Off from the list box. The Always Online feature can keep your web pages online when your site loses connectivity or times out.

• Development Mode Select On or Off from the list box. When Development Mode is on the cache is bypassed. Development mode remains on for 3 hours or until when it is toggled back off. Development mode is useful when updating the site so changes or errors can be seen immediately.

• Manage more Cloudflare settings at Cloudflare.com Click the OK button to be taken to the Cloudflare site for even more configuration options.
