A brief analysis of whether using iframe to call a page will cache the page_HTML/Xhtml_Web page production

Recently, I had a project that required using an iframe to call pages that change every day. Then I thought about whether the iframe would cache the page, so I wrote a demo to demonstrate it. The results are as follows:

If the src of the iframe is Static pages may be cached, because static pages have 200 and 304 status
If the src of iframe is a dynamic page, it will not be cached, because dynamic pages are all 200 status
The src of iframe is a pseudo-static page If so, you need to analyze whether the pseudo-static page will have a 304 status. If so, it will be cached

I hope it will be helpful to children who encounter the same problem.
