Announcing the Microsoft AJAX CDN
today the ASP.NET team launched a new Microsoft Ajax CDN (Content
Delivery Network) service that provides caching support for AJAX
libraries (including jQuery and ASP.NET AJAX). The service is
available for free, does not require any registration, and can be used
for both commercial and non-commercial purposes.
What does a CDN provide?
delivery networks (CDNs) are composed of "edge cache" servers that are
strategically placed around the world at key Internet network points.
These "edge cache" servers can be used to cache and deliver all types
a CDN can significantly improve a website's end-user performance, since
it enables browsers to more quickly retrieve and download content. For
example, instead of having a browser request for an image traverse all
the way across the Internet to your web server to download, a CDN can
instead serve the request directly from a nearby "edge cache" server
that might only be a single network hop away from your customer (making
it return much faster – which makes your pages load quicker).
I think it would be a great feature to have an EnableMicrosoftCDN option on the ScriptManager that will instead of loading the scripts as a resource from the local server to use the Microsoft CDN urls instead.
