It is the way the browser tells you the data has not changed so it will return the cached data. So it is a good news
Hi Deltakosh, Sorry for I didn’t explain it clearly，i know it will return the cached data, so i dont know why it take so long time.
Anyway you need to check what is happening with 304 response - How to Fix the HTTP 304 Not Modified Status Code - Kinsta
The 304 response still requires a request be sent to the server (to check if the content was modified). If the server’s request queue is taking a long time to handle requests, that would account for the time spent by your browser waiting to hear back from the server.
