What is a CDN?

CDN stands for Content Delivery Network. It is a network of servers, which are located all over of the world. The servers can also be called PoPs (Points of Presence) or edge servers. Every PoP in our network has its own cache memory. We use this network of servers for speeding up your websites or web services. Put in a simple way, we pull static files from your own “origin” server, and cache it in our PoPs. Then, when requested, we deliver these files to your clients from our nearest edge server to them. The results? Faster website and happier clients.

How does the CDN work?

Files are transferred via HTTP. The file pull is initiated when the file is requested from a client for the first time. At that moment, the file is cached and stored on the nearest datacenter to the client. Then, when the file is accessed by some other client from that area, the file is delivered from the cache rather than from your servers. However files are only stored for a set amount of time. You can decide how long we should keep the file cached by setting up cache-expiry in CDN settings. If you have “Cache-Control: max-age” or “Expires:” HTTP headers in place, we will give them a priority instead. So ideally, you will serve all your static files only through our infrastructure, saving you technical and financial resources.

CDN77 has a pay-as-you-go pricing model; no monthly fee and no commitments.

There are no hidden fees, you only pay for the outgoing traffic (traffic between our datacenters and your clients), which your visitors consume by downloading content such as images and videos that are on your website.

We deduct money from your prepaid credit for data your visitors actually receive - byte by byte as your traffic goes. Price per byte depends on the location of the server carrying out the request. We divide our data centers into 3 different price zones. Selecting a different number of servers in the same price zone will not result in higher costs.

You have full control over your data center selections and expenses in our CDN Resource settings.

We accept payments in USD, EUR or GBP and via credit card, PayPal or wire transfer.

First CDN configuration

First, you need to create a CDN Resource. Just click on the Add New CDN Resource button to proceed.

1. To begin, you need to set an origin. It can be your website URL, IP address of your server or CDN storage.
2. Next, you just need to set a label for the Resource.The label is there for you to easily identify different CDN resources in the client section.
3. When you are ready, hit Create CDN Resource button.

Your CDN should be up and running in less than 15 minutes after creation. You can check by accessing the CDN URL of the Resource (e.g. 1234567890.rsc.cdn77.org) and it will show your website, when the Resource is ready.

CNAME DNS configuration (optional)

CNAME is technically an alias for a different URL, so instead of using the CDN URL looking like “1234567890.rsc.cdn77.org” for your implementation, you can just use something like “cdn.example.com”. In order to make it work, you need to do these two steps:

1. In the Client Control Panel: Add a CNAME in our resource configuration.
2. With Your DNS (Domain Name System) provider: In your DNS control panel, create a new CNAME record, following the instructions displayed in the window. This is necessary so that the CNAME is in the DNS records. If you are unsure how to do this, contact your network provider
3. In the Client Control Panel: A window should pop up displaying “Your CNAME has been created”, right after hitting the “Add CNAME” button. You can display this pop up again, anytime you need, by clicking the Instructions tab.

As we do not have access to your DNS server, please contact your domain provider in case you are not sure, how to configure the DNS of your domain. All information you might need is located in the Instructions tab.

Please note that DNS changes could take up to 24 hours to fully propagate.

This is the very last step of the CDN integration.

The goal of this change is to replace all static content links on your website with a CDN77 link (or CNAME if you set it up in the previous step).

Here is an example of the CDN integration.
