java - Forcing Tomcat to use secure JSESSIONID cookie over http

Question

Is there a way to configure Tomcat 7 to create JSESSIONID cookie with a secure flag in all occasions?

Usual configuration results in Tomcat flagging session cookie with secure flag only if connection is made through https. However in my production scenario, Tomcat is behind a reverse proxy/load balancer which handles (and terminates) the https connection and contacts tomcat over http.

Can I somehow force secure flag on session cookie with Tomcat, even though connection is made through plain http?

Answer 1

In the end, contrary to my initial tests, web.xml solution worked for me on Tomcat 7.

E.g. I added this snippet to web.xml and it marks session cookie as secure even when reverse proxy contacts tomcat over plain HTTP.

<session-config>
    <cookie-config>
        <http-only>true</http-only>
        <secure>true</secure>
    </cookie-config>
</session-config>
