cookie secure flag missing
The secure flag is an option that can be set by the application server when sending a new cookie to the user within an HTTP Response. The purpose of the secure flag is to prevent cookies from being observed by unauthorized parties due to the transmission of a the cookie in clear text.
To accomplish this goal, browsers which support the secure flag will only send cookies with the secure flag when the request is going to a HTTPS page. Said in another way, the browser will not send a cookie with the secure flag set over an unencrypted HTTP request.
By setting the secure flag, the browser will prevent the transmission of a cookie over an unencrypted channel.
At a glance: The cookie will only be transmitted vie a secure (https) connection and by that will be encrypted during transfer.
<session-config> <cookie-config> <secure>true</secure> </cookie-config> </session-config>
String sessionid = request.getSession().getId(); response.setHeader("SET-COOKIE", "JSESSIONID=" + sessionid + "; secure");
Set the following in Web.config: <httpCookies requireSSL="true" />
