Browser Caching - External JS...

[ke...@healthfulpursuit.com]

Good morning all, 

This is my very first post here!

I've been working on optimizing our site and the Google Site Speed test recommended browser caching, so I did. 

Two issues:

#1. The Google Site Speed tool recommends changing the expiry on external JS files like https://www.googletagmanager.com/gtm.js?id=GTM-MHTQX7 and https://apis.google.com/js/plusone.js -- but I can't change those headers. 

#2. I changed the expiry on JS files and they now show as changed in the headers (Chrome/inspect), but the Google Site Speed tool still doesn't like them. Here is an example:

.../external-referral-links.min.js the headers show: Date:Thu, 08 Jun 2017 15:11:01 GMT  and   Expires:Sat, 08 Jul 2017 15:11:01 GMT   but the Google Site Speed tool lists it as... https://www.###.com/…external-referral-links.min.js?ver=1.0.2 (23.5 hours)

Thoughts?

You can't change what you don't host, but it's still a performance issue.

Why don't you try more than 24 hours? If I remember correctly, it wants more than 24 hours.

Hi Rick, 

Funny thing is, I've got it set to 1 month, and that's also how the expiry tags show up - in Chrome. 

But, interesting enough, I probably don't entirely understand what I added to my htaccess.

I'm not versed in Apache. I'll leave that to others. When I checked www.healthfulpursuit.com your cache looked good except for external scripts you load for social media, which you have no control over, unless you choose to host those files from your server.

Maybe go for the low-hanging fruit instead:

Properly formatting and compressing images can save many bytes of data.

Optimize the following images to reduce their size by 606.9KiB (75% reduction).

• Compressing https://www.healthfulpursuit.com/…017/06/The-Keto-Diet-Podcast-Blog_37.jpg could save 255.5KiB (73% reduction).
• Compressing https://www.healthfulpursuit.com/…-content/uploads/2016/12/Booklist2r2.jpg could save 83.2KiB (79% reduction).
• Compressing https://www.healthfulpursuit.com/…/uploads/mre-BalancedKeto-300x250.02.jpg could save 79.8KiB (79% reduction).
• Compressing https://www.healthfulpursuit.com/…nt/uploads/2016/12/ShoppingList1Rev1.jpg could save 77.6KiB (79% reduction).
• Compressing https://www.healthfulpursuit.com/…uploads/2017/05/Explorking-Follow-Us.jpg could save 57.1KiB (70% reduction).
• Compressing https://www.healthfulpursuit.com/…7/05/Healthful15_PerfectKeto_300x250.jpg could save 48KiB (73% reduction).
• Compressing and resizing https://www.healthfulpursuit.com/…tent/uploads/headshot-Martha-150x150.jpg could save 4.5KiB (73% reduction).
• Compressing https://www.healthfulpursuit.com/wp-content/uploads/megbain-150x150.jpg could save 1.3KiB (17% reduction).

Hello Kevin. The problem in your htaccess file is your "max-age", which is currently set to 84600 (23.5 hours). You can add to that, or like i did, get rid of it.
