Use a Content Delivery Network (CDN)

What cdn are you using?

Hello, Angelica. I am using MaxCDN.

Check the source code to see if the images/css/js are indeed coming from the cdn.
Can you provide a link to your site?

Everything “appears” to be OK and properly setup with my CDN. Maybe your eyes are better than mine though. Here’s my site: https://goo.gl/lHw8vO

Oh, nevermind…

It’s the infamous google js. Yslow is just saying that these files are not in your cdn:

I dont think there is a workaround for that. We cannot host those files generated by adsense…

You site is loading pretty fast, you do not need to get A/A score.

Thanks for the response. I do understand that 3rd party scripts and images cannot be directly loaded from a self-hosted server or CDN.

The problem is that it’s simply not detecting that I am using a CDN when I run a test at https://gtmetrix.com. But it most definitely should be.

Nope, as you cannot host these files or send it to a cdn because they are generated dynamically, Yslow “thinks” you just don’t want to do it.

It is says you are loading cdn for everything else BUT those files.

To score better you could remove adsense and disable the jetpack statistics.

Btw, you score better without the www. Go figure. You should try a redirect.

I see. That makes sense now. After watching all the videos on how to set this up, I don’t recall the users ever having any special plugins or 3rd party extensions enabled. I’m fine with this then.

Thanks kindly for all of your help, Angelica.

One last question…

Should there be version numbers at the end of these files? It seems to me that it would pose an insecurity. And no other sites I look at have them at the end of the files.

/wp-includes/css/admin-bar.min.css?ver=3.6.1′
/wp-content/plugins/jetpack/modules/widgets/widget-grid-and-list.css?ver=3.6.1′
/wp-includes/js/admin-bar.min.js?ver=3.6.1′

This will take care of it:

function remove_query_string( $src ){
     $parts = explode( '?ver', $src );
          return $parts[0];
}
add_filter( 'script_loader_src', 'remove_query_string', 15, 1 );
add_filter( 'style_loader_src', 'remove_query_string', 15, 1 );

Paste it on functions.php

Thanks, Angelica. Not doubting you by any means, but I doubt all the site owners that don’t have the version numbers displayed, haven’t manually added that to the core file. Where did you find that info? Does it boil down to a theme issue?

If you use w3 total cache, there is an option for that.

Check Fred’s answer.

I supposed some plugins do that, as well as cloudflare.

Thanks, Angelica.

Fred’s response in that topic is “Uncheck the “Prevent caching of objects after settings change” option on the browser cache settings tab.”

…which would mean to enable it. It’s currently already enabled in my settings.

Yeah, I know, that’s why I use the code above.

Thank you once again for your wisdom, Angelica. Question…would I have to implement that manual file edit every time I upgrade WordPress? Better yet, should I consult with the author of W3 Total Cache about the issue?
