How to Use Content Delivery Network to Host jQuery

Computer and computing are all about different software components responding exactly as desired. This, of course, refers to the behavior of the hardware utilities responding according to the codes being designed. However, as the codes are designed for a special purpose, there is a large list of web-based utilities in the computer today.

CDN or the Content Delivery Network is one such utility-based computing system, which is present in the entire system of computers. The purpose of CDN and the working of these systems all over global machines have given an extra nod to the users to breathe easy. The main purpose of CDN is to offer the clients and the users with a set of what is called as cache files.

Cache files are nothing but the temporarily stored files of a regularly visited online web page. The purpose of CDN is to implement the utility of these cache pages, which will allow the pages to get refreshed quickly, while some of the data’s will be stored in the browsers of the users pc.

For different browsers and sites, the codes of CDN are as follows,

For Microsoft,

<head>
  <script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.6.1.min.js"></script>
</head>

For Google:

<head>
  <script type="text/javascript"   src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
</head>

Vantage Points of CDN:

  • jQuery codes will take lesser time to get loaded. This is obvious since the cache files for appropriate users are stored in the browsers. The real-time required the page to load; even with a lagging internet, the connection is seamlessly abated.
  • The jQuery library will comprise the cached files in the browser. For an instance, for the website, which references the same for the jQuery library, will have the visitor in not downloading that particular jQuery library once more.
  • Most importantly, CDN has an unrivaled and free access to all the users, using a specified browser.

CDN is reportedly down for some reason. The technique comprises some of the popular jQuery features to work and execute. However, the users can have a backup, where CDN is loaded and the code will check if jQuery is loaded or not as follows,

<script type="text/javascript">

//jQuery.js still needs to be on your server.
if (typeof jQuery == 'undefined') {
  document.write(unescape("%3Cscript src='jQuery.js'" + "type='text/javascript'%3E%3C/script%3E"));
}
</script>

In this above code, the type of jQuery is checked to be undefined. In the next part, the document is taken into a write function, which contains the unescape code and will contain the codes of the previous CDN files.

CDN has some great news for both Microsoft and Google-based application users to host. These will simply act as a regular reference. The codes are different for both these sites, and the main portion remains intact irrespective of application.
