Does CDN caches html response?

[its.hitro]

My website shows messages pulled from the server every time it is viewed with a query string.

There might be time when user has no message, so the html page might look different. But after sometime the user will have 10 messages and the html page will look different.

So, I want to ask if Cloudflare CDN caches HTML of the webpage.

I am using standard caching level with no page rules set.

I am using standard caching level with no page rules set.

In that case HTML wont be cached.
