How does CloudFlare’s technology work?

CloudFlare is a CDN (content delivery network) with a security layer. Once a website is part of the CloudFlare community, its web traffic is routed through CloudFlare’s global network.

CloudFlare’s network stores a copy of static files closer to web visitors, which means they are delivered more quickly than before. CloudFlare caches resources such as CSS, JavaScript and images. CloudFlare’s technology automatically decides which resources to cache based on file extension names so there is zero configuration. CloudFlare also does compression for every request.

CloudFlare’s network also blocks threats and limits abusive bots before they hit the server, which means less wasted bandwidth and server resources.

Where are CloudFlare’s data centers located?

CloudFlare's network currently has 23 locations where it does caching and traffic filtering.

What types of websites can use CloudFlare?

Almost all websites can use CloudFlare. CloudFlare works for both static and dynamic websites.

CloudFlare is not suitable for websites that stream video or audio directly from their origin server. If a website uses YouTube or Vimeo for the videos embedded on your website, then that is compatible with CloudFlare. Streaming content should be on a subdomain CloudFlare doesn't touch, if a customer would still like to speed up the rest of their site.

My website has SSL. What should I do?

If you have SSL, your website can use CloudFlare, however there is an extra step. If your SSL is on its own sub-domain (i.e. SSL), then ensure that this sub-domain is marked with a gray cloud. If your SSL is on your root domain or www, then you have to upgrade to the paid, Pro service and follow the directions outlined here.

Are there domains I shouldn't enable with CloudFlare?

An orange cloud means that your web traffic will pass through the CloudFlare system making your site Faster, Safer and Smarter. A gray cloud means that your traffic will not pass through the CloudFlare system.

Only CNAME records have the option to be powered by CloudFlare, meaning that only CNAME records have the option of an orange cloud. However, not all CNAME records are appropriate to pass through the CloudFlare system.

To decide which records pass through the CloudFlare network, you need to understand what type of content appears on that subdomain. You should enable CloudFlare for any subdomain that gets web traffic. You should not enable CloudFlare for subdomains that handle non-web traffic, such as mail, ftp, and ssh. These types of records should be marked by a gray cloud.

Can I enable CloudFlare on a wildcard (*) sub-domain?

No, for security reasons, CloudFlare does not proxy traffic to a wildcard sub-domain. You have to explicitly list the sub-domain as a CNAME in your DNS records to be able to activate CloudFlare.

Can I enable CloudFlare on my root domain (i.e. mywebsite.com) that is an A record?

If you activate CloudFlare through Radium Hosting, CloudFlare can only accelerate and protect CNAMEs, not A records, which often includes the root domain. If you have traffic that goes to your root domain and you want to accelerate and protect the traffic using CloudFlare, you can add a redirect to ‘www’ in your .htaccess file. You should work with Radium Hosting, but as a general outline, a redirect looks like the following:

RewriteEngine On
# Rewrite added for CloudFlare - mysite.com
RewriteCond %{HTTP_HOST} ^mysite.com$ [NC]
RewriteCond %{SERVER_PORT} ^80$
RewriteRule ^(.*)$ http://www.mysite.com/$1 [R=301,L]

I activated CloudFlare from my Radium Hosting account. Do I also get an account on CloudFlare.com? What is the difference?

Once you activate CloudFlare on Radium Hosting you also get an account at www.cloudflare.com. The basic statistics and settings are shown in your Radium Hosting control panel. To see more statistics, your Threat Control panel and all the CloudFlare settings, you have to log in to your www.cloudflare.com account.

(Hint: To access your account the first time, enter the email address associated with your Radium Hosting account and use the “I forgot my password” feature).

I tried CloudFlare and have an issue. What should I do?

When you enable CloudFlare, there should be no noticeable difference to your website. If your site is loading slowing after enabling CloudFlare, there is most likely a problem. First, disable CloudFlare by clicking the orange cloud so it becomes gray. Second, report the issue to Radium Hosting. The Radium Hosting team will work with CloudFlare to resolve the issue.
