We recommend that you use js to write cookies on the client.

If you write a cookie on the server

I am using cookies for shopping cart, but all operations are front-end operations.
If you want to add a cookie and write data to the background, you can only use ajax to submit data.

Add it twice. we recommend that you paste the code.

If no event is triggered on a page, can the server obtain the cookie value transmitted by js?
You can use the setinterval () provided by JS to solve this problem.
