I use the W3 Total Cache Plugin for Wordpress.
If I enabled "Cache SSL (https) requests" in W3 Total Cache and testing my site at https://securityheaders.io for security reports, then I get only one time a positive response.
Anyone know I can fix that?
The problem is when I disabled the SSL Caching the 304 header (Last-Modified) don´t works anymore.
If I clear the cache then it works again and the response is positive. But i can´t clear the cache every time after an request for every user.
Or I have a wrong thought ?
