We are trying to set Http response security header “private, no-cache, no-store, must-revalidate” but the response header is still showing “Cache-Control: no-cache” only.
Vaadin version :: 7.2.6
Code ::
response.setHeader(“Cache-Control”, “private, no-cache, no-store, must-revalidate”); // HTTP 1.1.
response.setHeader(“Pragma”, “no-cache”); // HTTP 1.0.
response.setHeader(“Expires”, “0”); // Proxies.
kindly help us to resolve this issue.
