Where do you include the jQuery library from? Google JSAPI? CDN?

Question

There are a few ways to include jQuery and jQuery UI and I\'m wondering what people are using?

• Google JSAPI
• jQuery\'s site
• your own site/serv

Answer 1

Pros: Host on Google has benefits

• Probably faster (their servers are more optimised)
• They handle the caching correctly - 1 year (we struggle to be allowed to make the changes to get the headers right on our servers)
• Users who have already had a link to the Google-hosted version on another domain already have the file in their cache

Cons:

• Some browsers may see it as XSS cross-domain and disallow the file.
• Particularly users running the NoScript plugin for Firefox

I wonder if you can INCLUDE from Google, and then check the presence of some Global variable, or somesuch, and if absence load from your server?
