Answer 1

On sucess;

response.setHeader("Set-Cookie", "fileDownload=true; path=/");
response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate");

On error

response.setHeader("Set-Cookie", "fileDownload=false; path=/");
response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate");

Use "Cache-Control" only if will exists anothers requests.
