Consider auto-checking latest CDN version

[drublic]

Just a few days ago I recognized that the footer of the page linked to jQuery 1.9.0 instead of the latest version on the Google CDN. This was clearly because 1.9.1 was only up for two days or so yet. (Fixed by @ajpiano asap in 3fc5185 tho.)

I was wondering if it would make sense to update the link to the CDN automatically with a small script (either JS or PHP).

Some time ago I implemented something similar in Is Mothereffin jQuery Up. This implementation in JS checks the latest jQuery version from the jQuery CDN and then tries to get the same version from other CDNs. These requests can take a while tho.
In PHP it might be easily done with some curl action.
As a fallback the manually updated CDN link could be available before the requests are completely done.

This is just a suggestion and pretty low priority I think.

I think we should continue manually tracking versions. This is an issue that only occurs a few times a year and isn't a huge issue. Alternatively, jQuery core can stop using the Google CDN, like jQuery UI has done.

@ajpiano @dmethvin Thoughts?

Thanks for the feedback.
Just for clarification: updating the script in the file itself wouldn't make much sense to me. I was just talking about the input field.

But yeah… the problem only occurs every once in a while. So maybe it's not worth the effort.

I know you're only talking about the input field. Look at jqueryui.com, we link to the jQuery CDN because it's always up-to-date :-)

Ah yea… True that. There could still be a check for the version tho ;)
