Cross Domain Loading Using DNS-Prefetch Link Tag For Speeding Up Your Website.

RussianRoot 20/02/2013 0

While walking in the web I have analyzed lots of websites like twitter, amazon, facebook.

On some of them i have found very interesting link tag with dns-prefetch attribute.

This attrebute make very interesting job! For example if you are using CDN’s, you can
pre-resolve server’s IP address before the browser actually do a request on it. It saves a bit of time
and makes your website much faster.

Here i have some examples of dns prefetching:

-Amazon.de:

 

-Themeforest.net:
