title: JSESSIONID Cookie with Expiration Date in Tomcat
body: <p>What's the best way to set an expiration date for the JSESSIONID cookie sent by Tomcat for a servlet session? </p>
  
  <p>By default, the expiration date of the cookie seems to be 'session', which means that the session disappears in the client as soon as the browser restarts. But I would like to keep it open for 12h, even after a browser restart (and would then configure the session timeout in the server accordingly). </p>
  
  <p>Is there any way to set an expiration date within Tomcat, e.g. using some configuration option or extension module? Or is there a reliable way to set an expiration date for JSESSIONID using a Servlet filter?</p>
