Hello, I am trying to set up caching of my test page https://free-psd-templates.com/test.php
My task is to make it so that when generating a page, it would be given etag or Last-Modified (or whatever). But after refreshing the page, this title will change. And I would like cloudflare.com to update Edge TTL of this page on the server.
I’ve been sitting for more than a day with this task, maybe someone has at least one idea how to do it?
