The same link returns different results:
The above is requested by the same URL, but the returned results are different. The frequency of the first result accounts for 90%, and the frequency of the second result: 10%.
What is going on? Is it an nginx cache problem?
There are so many funny friends. What I'm returning is something static.

Forget it, no one is paying attention to the question. I also deleted some private stuff. Case closed.

Give you a magical URL: https://segmentfault.com
You will find that almost every time you request this page, the content you get is different. Isn’t it a surprise?

Explanation is that the homepage is dynamic content, JD.com’s homepage is also like this

It is normal for the same link to return different things.
Unless it is static fixed content.

This is normal.
For example, on the product list information page, when the administrator adds a new product during the second visit, more data will be displayed.
Another example is if the website is load balanced, and random servers return results for each visit, and the databases connected to these servers are not the same, this kind of thing will happen.
