SV-57633r5_rule Session only based cookies must be disabled.

Vulnerability discussion

Policy allows you to set a list of URL patterns that specify sites which are allowed to set session only cookies. If this policy is left not set the global default value will be used for all sites either from the 'DefaultCookiesSetting' policy if it is set, or the user's personal configuration otherwise. If the 'RestoreOnStartup' policy is set to restore URLs from previous sessions this policy will not be respected and cookies will be stored permanently for those sites.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
