after nginx sets the reverse proxy, the request shows Provisional headers are shown
what to do

that is Request Headers , which has nothing to do with the server
because your request is not sent to the server, but (from disk cache) , so Chrome can only display temporary headers

.

if you want to test, but the browser has cache, check Developer Tools Disable cache
if this page should not have cache, it is because your backend does not have the correct Cache-Control header
