Content Delivery Networks Explained in Simple Terms

Do you have slow loading Websites? Then you should have to read this. Slow loading website means unhappy customers as the world is moving fast people normally stick to fast loading websites rather than slower loading websites. Even google gives priority to faster loading websites. So is there any way to make the website to load faster?

Yes CDN – Content Delivery Network is the solution for faster loading websites. The content delivery network (CDN) a collection of web servers distributed across multiple locations to deliver content more efficiently to users. The server selected for delivering content to a specific user is typically based on a measure of network proximity. For example, the server with the fewest network hops or the server with the quickest response time is chosen.

If you noticed technotricks now the page loading is faster than ever. Yes Now Technotricks in now CDN enabled powered by MAXCDN to entertain more audience.

Here is a animated video explains How CDN works

the cost of a CDN service can be prohibitive, but as your target audience grows larger and becomes more global, a CDN is necessary to achieve fast response times. Switching to a CDN is a relatively easy code change that will dramatically improve the speed of your web site.

The CDN is basically a caching system that directs your customers to the nearest caching server (or node). As the customer accesses your website, they retrieve content from the node instead of the origin server, reducing the load on that server and allowing for much faster delivery of the content. With On-demand Propagation, content from your origin site is instantly pushed out to each caching server only when it is being requested from a specific geographic location. This results in increased performance and cost savings. Our online CDN Control Panel provides you with real-time information and easy-to-use tools for monitoring, distributing, and managing your content.

Every site starts somewhere, and the first step to getting your site running on the CDN is the hostname. There are two basic rules to follow:

i. The site needs to exist within a single hostname. For example, if you set up ‘’ will cache elements under only. It will not cache its linked banner site or its development blog at You can always add additional hostnames or change existing ones by contacting your sales representative.

ii. The site should not be a domain name. Attempts to setup a cache of ‘’ will break the DNS records for ‘’. Only leaf host names such as ‘’ or ‘’ will work by default.

If you have an issue with either of these points, there are some slightly more involved technical workarounds that can be employed at ZNetIndia you can just let us know you have a special requirement and we will do our best to meet your needs.
Using Content Delivery Network will Speed up your tasks

The user’s proximity to your web server has an impact on response times. Deploying your content across multiple, geographically dispersed servers will make your pages load faster from the user’s perspective. But where should you start?

As a first step to implementing geographically dispersed content, don’t attempt to redesign your web application to work in a distributed architecture. Depending on the application, changing the architecture could include daunting tasks such as synchronizing session state and replicating database transactions across server locations. Attempts to reduce the distance between users and your content could be delayed by, or never pass, this application architecture step.

Remember that 80-90% of the end-user response time is spent downloading all the components in the page: images, stylesheets, scripts, Flash, etc. This is the Performance Golden Rule. Rather than starting with the difficult task of redesigning your application architecture, it’s better to first disperse your static content. This not only achieves a bigger reduction in response times, but it’s easier thanks to content delivery networks.

    Incidentally, I wrote a series of blog posts (two of which have been published thus far) that outline some of the technical considerations in evaluating performance testing of CDNs.

    In additional to traditional caching services, CDNetworks also offers Dynamic Web Acceleration (DWA), which offers middle-mile acceleration of content between your origin datacenter and end users. This allows dramatic acceleration of the delivery of non-cacheable assets that must be generated anew each time by your origin servers (which includes most HTML pages written in a server-side scripting language).

    CDNetworks also offers a Cloud DNS solution that overcomes the limitation mentioned in this article about not being able to run the SOA domain on a CDN. By using CDNetworks as your authoritative DNS provider, you can run your site through the CDN as easily as you could your site.
