Hi,

You can achieve this by doing these:

1. Adding this meta tag in index.html file.

<meta http-equiv="cache-control" content="no-cache, must-revalidate,no-store">
<meta http-equiv="expires" content="0">
<meta http-equiv="pragma" content="no-cache">

    Or 2. You can create custome HTTPInterceptor to modify all requests in your application. like:

 intercept(req: HttpRequest<any>, next: HttpHandler) {
    const httpRequest = req.clone({
      headers: new HttpHeaders({
        'Cache-Control': 'no-cache,must-revalidate,no-store', 
        'Pragma': 'no-cache' 
      }) 
});
