Can someone help me understand this "Browser Cache" setting for CSS and JS? (So I can decide what's the best option)
[ ] Prevent caching of objects after settings change - Whenever settings are changed, a new query string will be generated and appended to objects allowing the new policy to be applied.
I am quite new at this. I am using WP 3.1.3, Polished theme from Elegant Themes, W3 Total Cache 0.9.2.3, WordPress SEO 0.4.2, on a Windows 7 x64 machine and have shared hosting using Linux/Apache. Page Speed in Chrome is 80. Page load time: 12 seconds.
