bind GENERATE and CDN

In our advertising network we use landing page with great number of images.

And previous team use domain static.OURDOMAIN.net for CDN. But modern browsers open from 4 to 6 simultaneous connections to one domain name. So it takes huge ammount of time to load all page.

i.e. 4 images start loading, browser waits for 1 image load complete, next image loading.
Damn not good and extremely slow 🙂
so use force Luke:

bind zone:

$GENERATE 1-64 static$      IN  A   1.1.1.1     ;s7
$GENERATE 1-64 static$      IN  A   2.2.2.2     ;sgr1
$GENERATE 1-64 static$      IN  A   3.3.3.3     ;sf6
$GENERATE 1-64 static$      IN  A   4.4.4.4     ;sf31

And Use something like http://static.’random(1-64)’.OURDOMAIN.net/IMAGE.PNG in application code.

We significantly speed up page loading. (up to 3 times).
