Serve static assets with an efficient cache policy

Hello @knzzz

Thank you for reaching out and I am happy to assist you with this.
I’ve checked the test results and your website and I can confirm that the expires header and cache-control header is not set for static files.
Can you please check if Browser Cache is enabled in Performance>Gneral settings? If so, check if the “Set expires header” and “Cache-control header” is enabled in Performance>Browser Cache, sections “CSS&JS” “Media&Other files” and “HTML&XML”. If not, enable those, save all settings and purge the cache and let me know if the problem persists.
Also, make sure that you don’t have any custom Browser Cache rules added to your .htaccess file to avoid any potential conflict with W3 Total Cache rules.

I hope this helps!

Thanks!

Hello,
Thank you for your reply. Yes, those options are already checked. I’ve purged the cache.

Hello @knzzz

Thank you for the information.
Can you please check and share the content of the .htaccess file so we can make sure that the W3TC rules are set for Browser Caching?
If the rules are there, there is a chance that some .htaccess file on a higher level or httpd.conf file is handling those rules.
I can see that the Etag, gzip compression and last modified header are set on the static files.
Try enabling “Set W3 Total Cache header” in Performance>Browser Cache, general section, save all settings and purge the cache, so we can confirm that the rules are taking effect.
Thanks!

Enabled Set W3 Total Cache header and purged the cache. Here is the .htaccess file

Hello @knzzz

The .htaccess rules are there and look fine.
The configuration directives found in a .htaccess file are applied to the directory in which the .htaccess file is found, and to all subdirectories thereof. However, it is important to also remember that there may have been .htaccess files in directories higher up. Directives are applied in the order that they are found. Therefore, a .htaccess file in a particular directory may override directives found in .htaccess files found higher up in the directory tree. And those, in turn, may have overridden directives found yet higher up, or in the main server configuration file itself.
You should check for any .htaccess files in the directories above and also check the main httpd.conf.

Thanks!
