Cache issue on webapp


I deployed a small project game on a web server (provided by ionos). The app works fine, however, what I noticed is that all the requests done to the database (done through webservices on the server side and Ajax calls in nsb with the POST method) the results are cached, so if I request is again, the old information still showing.

If I close the chrome tab, and reopen it seems that the cache is cleared because the shows the new information. This is an awful workaround, but it works.

Is there any nice way to do this from the app side?

Best Regards,

One trick is to append a datestamp to the query string. That insures that each request is unique.
