Google CDN is a popular choice found at http://code.google.com/apis/libraries/devguide.html. Just choose the Library you need and grab the link.
To add the library to your page replace what you normally do:
It would be better to leave out the “https:” so that your page will use either “https:” or “http” depending on the type of request the page is making.
The benefits of using CDN over hosting your own is that the browser will download the file in parallel with other js files if they are hosted on a different url. Also the file will be cached if the user has downloaded that file from visiting a different website.
There are other CDNs available including microsoft, but with google, you can use
just 1.6 in the path version name and you will get the latest in the 1.6x series. Or better yet, just “1” and it will always grab the latest before “2.x.x”
