thank you @ragtech. @ thegingeek, did you try?

Thank you @ragtech I am traveling at the moment and will take a look first thing tomorrow morning and feed back, appreciate your help.

Yes, added the code below to my “.htaccess” file…

<IfModule mod_headers.c>
  <FilesMatch ".(js|css|xml|gz|html)$">
    Header append Vary: Accept-Encoding
  </FilesMatch>
</IfModule>

…Improved my “Specify a Vary: Accept-Encoding header” score to “A” (93)

Also, use https://tools.pingdom.com/ it’s much better than Google’s “PageSpeed Insights” it also will show you your Google PageSpeed Performance Grade and so much more!

Hi Guys
I added the code to my .htaccess but get the same result ??

<IfModule mod_headers.c>
<FilesMatch “.(js|css|xml|gz|html)$”>
Header append Vary: Accept-Encoding
</FilesMatch>
</IfModule>

Was there a particular section within the .htaccess file I should place it?

I tried both the top and the bottom of the .htaccess file.

Pingdom still shows this…

The following publicly cacheable, compressible resources should have a “Vary: Accept-Encoding” header:

Be great if you could take another look for me.

Thanks

There is “No” particular area the code needs to be placed within your “.htaccess” file.

And do NOTE: I too still get the “The following publicly cacheable, compressible resources should have a “Vary: Accept-Encoding” header:” message!

It was the score that was improved… As I mentioned above – it improved my score to “A” (93)… (from what was a “D”) – If you’re trying to get to a score of 100%; you may have to look at what files (Most likely they’re JS files) are causing the low scores.

For instance, Google Maps & Twitter JS files seem to still show up for me. It may also include removing one or more Plugins… you may even need to remove some HTML.

Pingdom shows you the specific files you’ll need to deal with (by clicking the Down Arrow). Find what those files are linked to and then you’ll have to make the choice (As an example… do I want that Map or Twitter button or can I do without it on that page).

For me getting my score from a “D” to an “A” was good enough… I was not looking to get to 100%!

My guess is it would be the last one “https://z-na.amazon-adsystem.com/widgets/onejs?&#8221;

Search Google for “Specify a Vary: Accept-Encoding header https://z-na.amazon-adsystem.com/widgets/&#8221; and see what turns up. I found this on a quick search https://amzn.to/2H7qp9Y
