set cache-control to external resources?

@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>
Solution

  • 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.
