    • Field Detail


        public static final String FORCE_SESSION_TRACKING_BY_COOKIE_PROP
        System property name to force the session tracking by cookie. This prevents Tomcat to use the URL tracking in addition to the cookie by default. This could be useful for instances that requires to have the SuspiciousRequestFilter.allowSemicolonsInPath turned off.

        If you allow semicolon in URL and the session to be tracked by URL and you have a SecurityRealm that does not invalidate session after authentication, your instance is vulnerable to session hijacking.

        The SecurityRealm should be corrected but this is a hardening in Jenkins core.

        As this property is read during startup, you will not be able to change it at runtime depending on your application server (not possible with Jetty nor Tomcat)

        When running hpi:run, the default tracking is COOKIE+URL. When running java -jar with Winstone/Jetty, the default setting is set to COOKIE only. When running inside Tomcat, the default setting is COOKIE+URL.

        public WebAppMain.FileAndDescription getHomeDir​(javax.servlet.ServletContextEvent event)
        Determines the home directory for Jenkins.

        We look for a setting that affects the smallest scope first, then bigger ones later.

        People make configuration mistakes, so we are trying to be nice with those by doing String.trim().
