Leverage browser caching

There are also Minify JS things…..

and “The following resources are missing a cache validator. Resources that do not specify a cache validator cannot be refreshed efficiently. Specify a Last-Modified or ETag header to enable cache validation for the following resources:”

Can any of these 3 issues be handled with W3?

Hello @sbraunm

Thank you for your inquiry and I am happy to help you with this.
As you can see these are all external resources and that being said, W3 Total Cache or any other plugin for that matter cannot handle those files because they are coming from the external server.
In Performance>Browser cache you can set:
Set Last-Modified header
Set expires header
Set cache control header
Set entity tag (ETag)
Enable HTTP (gzip) compression
This will take care of all static files on your server setting the expires header, cache-control, gzip, ETag, etc.
As for Minify JS things, can you please be more specific?
Thank you!

Hello Marko, and thanks for your continuos support for W3.

You can see the minify list here:

Hello @sbraunm

Again all external resources and cannot be handled by W3 Total Cache.
Your test results are great. https://gtmetrix.com/reports/www.nationalallergyperu.com/gP1tADLE
Your website loads under 2s and the overall score is 93 which is great.
Those recommendations for minifying suggest reducing the size by 1% which is basically a statistical error and it would not increase the score.
You might want to enable the “Disable Emoji” option in Performance>User Experience to remove emojis (unnecessary).
To conclude, your website load speed and score are great and the user experience is awesome.
Thank you!

2secs? I see around 6secs everytime and can not reduce it. In any case there nothing else to do at W3 level, right?

Hello @sbraunm
Yes as you can see in the test results.
No, nothing else can be done.
Thanks!

got it, thanks Marko!
