It is possible to prevent other websites from displaying content from your website in an iframe using a technique called \"frame busting\" or \"clickjacking defense.\"

Frame busting works by detecting if a web page is being displayed within an iframe and then redirecting the browser to the same content but outside of the iframe. This prevents the other website from displaying your content in their own frame.

To implement frame busting, you can add JavaScript code to your web page that detects if it is being displayed within an iframe and then takes appropriate action. Here is an example of frame busting code:

if (top != self) {
  top.location.href.location.href;
}
