JSESSIONID Cookie with Expiration Date in Tomcat
As of Servlet 3.0, this can simply be specified in the web.xml: <session-config> <session-timeout>720</session-timeout> <!– 720 minutes = 12 hours –> <cookie-config> <max-age>43200</max-age> <!– 43200 seconds = 12 hours –> </cookie-config> </session-config> Note that session-timeout is measured in minutes but max-age is measured in seconds.
