Leverage browser caching for external JavaScripts

[HafezNa]

Hi friends

I optimized my site (HafezNa.ir)...for all items
but I get a "Leverage browser caching" warning for an external JS
(for example for "google analysis" or statcounter)

how can solved it??

You can't. Just make sure you are loading the scripts asynchronously and that's the best you are going to be able to do.

Looking at your site, one big win you can get will be fixing the blocking issue with IE conditional comments. You have:

Code:

<!--[if IE 7.0]><style>.clearfix { display: inline-block; } /* IE7xhtml*/</style><![endif]-->

directly after your external css and that is causing all versions of IE to not load the rest of the content on the page until the css finishes loading. If you add an empty conditional comment to the top of the page it should "unstick" IE and load more in parallel.
