Hi,

I'm trying to address issues found via Google's PageSpeed.

I was able to address image expiration via htaccess, but I'm at a loss when it comes to resolving CSS/JS issues.

Here is what google complained about:
SHOULD FIX:
Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
/jscript/back_to_top.min.js (5 minutes)
/jscript/categories_css.js (5 minutes)
/jscript/cbpFWTabs.js (5 minutes)
/jscript/css_browser_selector.js (5 minutes)
/jscript/jquery.flexslider.js (5 minutes)
/jscript/jquery.slimmenu.min.js (5 minutes)
/jscript/jscript_imagehover.js (5 minutes)
/css/responsive.css (60 minutes)
/css/responsive_mobile.css (60 minutes)
/css/style_imagehover.css (60 minutes)
/css/stylesheet.css (60 minutes)
/stylesheet_categories_css.css (60 minutes)
/css/stylesheet_dotline.css (60 minutes)
/css/stylesheet_flex.css (60 minutes)
/css/stylesheet_manufacturers_all.css (60 minutes)
/css/stylesheet_zen_colorbox.css (60 minutes)
• http://www.google-analytics.com/plugins/ua/ec.js (60 minutes)
• http://www.google-analytics.com/analytics.js (2 hours)
Funny that they complain about their own js.

Anyway, I'm unclear about what to do. To me, 60 minutes seems very short for CSS. And I'm 100% clueless about what a reasonable JS expiration should be. And I can't for the life of me figure out where the expirations for these files live. It must be central because all CSS and all JS have the same setting.

Can somebody explain what I'm supposed to do about this?

Thanks!
