Question How to use Clear-Site-Data header rule to clear browser cache

Plesk Obsidian v18.0.57
Hello,

I try to add Clear-Site-Data rule to the header of a domain, without success.


Here are the Apache cutoms header rules I have :

Code:
X-Frame-Options: SAMEORIGIN
X-Content-Type-Options: nosniff
Referrer-Policy: no-referrer-when-downgrade
Strict-Transport-Security: max-age=31536000
X-XSS-Protection: "1; mode=block"
Feature-Policy: vibrate 'self'; usermedia *;
Cache-Control: no-cache
Clear-Site-Data: "cache"

HTML page has those META :

Code:
<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="0">

This doesn't seem to work: if a user initially had the HTML page cached in its browser, the directive does not clear its cache.

Test has been done with Google Chrome on client side.
Debian Plesk Obsidian v18.0.57 on server side.

I'm probably making a mistake somewhere.

Thanks for help.
 
Did you check if the header is actually present in your browser when you visit your domain?
