How JsLoad Works

We all use javascript libraries heaviliy, and most javascript libraries take quite a lot of resources to load up. When I say that, imagine a 50kb javascript library, accessed by 1,000 unique users each day. Thats a whopping 50Mb per day in just downloading the javascript library - the equivalent of 1.5Gb per month! You can really use up a lot of bandwidth this way. To reduce your bandwidth, why not load the javascript libraries from another server?

Well, with the advent of google app engine, there is now a solution! JsLoad (http://jsload.net) is a google app engine solution that seamlessly integrates javascript libraries loaded from google servers into you site. No more serving large javascript libraries from your own server, and you can save quite a lot of bandwidth (read = money) with this, with the comfort of knowing that Google's servers are hardly down.

So next time you are considering loading a common javascript library such as Prototype or Scriptaculous, look at this solution to save you bandwidth, and load up times. You can bet that the latency from Google servers are better than your own servers. And they are more reliable.
