I've been having this issue for a while now, but unfortunately it appears the issue persists in the latest version of Safari (Sonoma 14.0). When I refresh a webpage for a site with dynamic content, it looks like it's refreshing the page, but it instead loads what I assume is cached content.

For an example of this, check https://old.reddit.com/r/politics/new. Wait a while to make sure new content has been posted to the site, then click the refresh button. Over 90% of the time, the page will load the same content. In my case this morning, it is still loading posts from last night. If I open the page in another browser, I get the new posts.

For reference, I am loading the page in a tab group I call my "daily" group, and I have extensions 1password and "Dark Mode" installed. I also have advanced tracking and fingerprinting protection enabled, which interestingly, causes some sites to kick me out of my account after some time, but not in others.

Has any one else seen this issue, and what can I do to resolve it?
