set cache-control to external resources?

Question

@tools.pingdom.com I get a warning in leverage cache-control because of these resources:

http://code.jquery.com/jquery-1.6.2.min.js
http://www.google-analytics.com/ga.js
http://edge.sharethis.com/images/spinner.gif
http://w.sharethis.com/button/buttons.js

Which are not in my host.

What can I do about this?

This is the beginning of my htaccess:

# 480 weeks
<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|css|swf)$">
Header set Cache-Control "max-age=290304000, public"
</FilesMatch>

# 1 weeks
<FilesMatch "\.(js)$">
Header set Cache-Control "max-age=604800, public"
</FilesMatch>

You can't control the headers sent from a server that you don't control.

In other words, either host a copy yourself or there's nothing you can do about it.

You can grab the code from the resources and serve them from your site directly, in these way you can manage the cache, but if some update occurs from the sites related to the resources, you miss it, or you have to control everytime ..chose at your convenience.

But probably it's not a good Idea to cache the google analytics script, right? it's probably dynamic.. – Toni Michel Caubet Sep 21 '13 at 08:12

You can try copy their scripts and host them youself. Just write a script and add it to cron to load new versions automaticly. Working on it now myself.
