Rshiny security

A security scan on the Rshiny server returned the following error messages:

Update Cache-Control http header to include no-store directive. The purpose of this directive is to prevent the inadvertent release or retention of sensitive information. The suggested HTTP response headers are: 
Cache-Control: no-cache, no-store 
Expires: 0 
Pragma: no-cache 


The new Content-Security-Policy HTTP response header helps you reduce XSS risks on modern browsers by declaring what dynamic resources are allowed to load via a HTTP Header. CSP makes it possible for server administrators to reduce or eliminate the vectors by which XSS can occur by specifying the domains that the browser should consider to be valid sources of executable scripts. A CSP compatible browser will then only execute scripts loaded in source files received from those whitelisted domains, ignoring all other script (including inline scripts and event-handling HTML attributes).

Any help on how to solve them?
