RESEARCH 》 How to check a website using CDN ?

If you are new to CDN Technology, you can read the Introduction of CDN (Content Delivery Networks or Content Distribution Networks) over HERE.

Using a CDN for a website is a always suggested based on the popularity of your website. But do you know how to check if a website is using a CDN ?

Here is how you can check quite easily.

Lets take for example Facebook. Open the Facebook website in your browser.

Do right-click and select the “View Page Source” option in the menu:

Now search for keywords such as “cdn”, “edge”, etc. You can find the website resources (such as scripts/images/etc) should be pointing to alternative links as shown below:

In this case Facebook contains the resources with URLs pointing to CDN hosted locations. As you can see it has the location “”. This stands for: Static Akamai Facebook CDN. So this is a clue that Facebook is majorly hosted on Akamai CDN.

But one should also understand since Facebook is so massive, Facebook may/will contain its own CDN (or cloud sort of) infrastructure. But if this goes beyond a massive scale, certainly they can get outside world CDN subscriptions as in this case they got via Akamai.

Let us see another example such as the website ComputerWorld online magazine.

In this case ComputerWorld is using the is run by Akamai Technologies more specific for AD content. So once again we can see how a website uses a CDN Service.

In the case of Linkedin, it uses the Limelight CDN service/vendor. You can see the resource URLs containing

TOFFEE WAN Optimization software development, roadmap, live-demo - Update: 06-Nov-2016 ↗
Saturday' 13-Mar-2021
Here are some of the screenshots of the new upcoming TOFFEE WAN Optimization release and live demo.

TOFFEE Benchmarks :: TOFFEE-1.1.28 ↗
Saturday' 13-Mar-2021
Here is the TOFFEE WAN Optimization benchmarks of the TOFFEE version: TOFFEE-1.1.28. This is the current TOFFEE development version till date (2-Jul-2016). This is a HPC TOFFEE variant meant for high-end custom build servers and high-end desktops (i.e High Performance Computing a.k.a HPC). TOFFEE built this way often needs customized kernel compilation and build such as processor specific and hardware specific tune-ups since it is highly CPU intensive (if not offloaded via Hardware Accelerator Cards).

TOFFEE-DataCenter - First Live Demo and software development - Update: 26-Aug-2016 ↗
Saturday' 13-Mar-2021
Today I have done a test setup so that I can able to connect my Android Samsung Tab via TOFFEE DataCenter. Below is my complete test topology of my setup. For demo (and research/development) context I configured TOFFEE DataCenter in engineering debug mode. So I do not need two devices for this purpose.

Building my own CDN - Google PageSpeed Insights - Update: 22-Jul-2016 ↗
Saturday' 13-Mar-2021
Ever since after I launched my new The TOFFEE Project website on 1-May'2016, I can see there is a steep increase in traffic. Soon after the launch when I monitored its Alexa rankings it was reporting about 12 Million or so. But once it is getting more and more traffic the Alexa rankings shot up and now currently it shows around 2 Million (as on 22-July-2016). Alexa is an excellent tool to monitor your overall website global ranking and indirectly its performance. Unlike Google Analytics which is bound one or other way into Google's SEO. Alexa gives you a second opinion about your website's growth.

TOFFEE-Mocha WAN Emulation software development - Update: 1-July-2016 ↗
Saturday' 13-Mar-2021
Today I got a feature request from Jonathan Withers. Jonathan is from a company called MultiWave Australia. He said he is able to get the TOFFEE-Mocha Raspberry Pi setup up and with that he is able to emulate geostationary satellite link. But he requested me is there a way to extend the constant packet delay from 40mS to 500mS. So as a part of his request I supported the same in the current ongoing development version of TOFFEE-Mocha.

First TOFFEE-Mocha Code Release ↗
Saturday' 13-Mar-2021
TOFFEE-Mocha is my dream project which I thought working on it since several years. I want to make a WAN emulation software which is straight forward and simple to use. I used tc scripts along with iptables for testing my TOFFEE (and TrafficSqueezer before TOFFEE) and I am not quite satisfied with the same. As one can understand these scripts are not meant for WAN emulation.

TOFFEE-Mocha WAN Emulation software development - Update: 16-June-2016 ↗
Saturday' 13-Mar-2021
I started TOFFEE-Mocha WAN Emulation software development on 1-June-2016. I took the existing TOFFEE components as a base. Although the TOFFEE-Mocha is entirely an independent fresh Open-Source WAN Emulation solution. Ever since I am in the process of defining and inventing features. So far I come up with the most important feature which is expected to be present in any WAN Emulation software is the packet delay option.

TOFFEE with Hardware Compression and Decompression Accelerator Cards ↗
Saturday' 13-Mar-2021
You can build a basic TOFFEE WAN Optimization hardware completely in software layer (i.e its networking data-plane and control-plane). And if you are a product manufacturer you can make commercial WAN Optimization products with TOFFEE with software layer alone. And if you choose to improve its performance, you can use any third-party PCIe Compression Accelerator cards.

Introducing TrueBench - a high resolution CPU benchmarking system ↗
Saturday' 13-Mar-2021
TrueBench is an unique open-source benchmarking system in which the core system performance and efficiency parameters are measured at extreme high resolution in the order of several million/billion µ-seconds for a given specific task. TrueBench is a part of The TOFFEE Project research. With TrueBench Raspberry Pi 3, Raspberry Pi 2B, Raspberry Pi 2 and other embedded SoC devices are benchmarked and you can do a comparative analysis with standard mainstream x86 devices.
