Google has announced that they are providing versioned hosting of the major AJAX libraries. Very cool! They’ll put the libraries on their servers, so they’re fast to access from anywhere in the world, and they promise to keep all versions going forward, so you can always get the one you want.
The big win, according to the article, is that browsers will already know that they have a version of a library if many apps use the same libraries from the same host. In that case, the browser won’t even have to download the library when the app requests it.
My favorite quote from the discussion: “Is this charity, or world domination?”
