Below I will bring you a summary of 5 ways to solve caching using Ajax. I will share it with you now and give it as a reference

1. Add anyAjaxObj.setRequestHeader(“If-Modified-Since”,”0″) before sending the ajax request.

2. Add anyAjaxObj.setRequestHeader(“Cache-Control”, “no-cache”) before sending the request via ajax.

3. Add a random number after the URL: “fresh=" Math.random();.

4. Add the time after the URL: "nowtime=" new Date().getTime();.

5. If you are using jQuery, just do $.ajaxSetup({cache:false}). In this way, all ajax on the page will execute this statement and there is no need to save cache records.

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
