For every SharePoint page, the browser loads a new instance of the core.css (or corev4.css) file.

Is there a way, in the Master Page, to enable caching for this file?

Are you sure that the browser loads a new instance everytime? becasue i think it already cashes all the heavy files like core, ribbon css as well as all the js files.

What makes you think that? – Christophe Sep 14 '10 at 4:10
Update: I took a closer look, and you're right: the file name and revision number stay the same when you navigate a site. Thanks! – Christophe Sep 14 '10 at 4:20
