QlikView: Persistent cookie with "expires=" tag does not contain any confidential information

Cookies are small bits of data that are sent by the web application but stored locally in the browser. This lets the application use the cookie to pass information between pages and store variable information. The web application controls what information is stored in a cookie and how it is used. Typical types of information stored in cookies are session Identifiers, personalization and customization information, and in rare cases even usernames to enable automated logins. There are two different types of cookies: session cookies and persistent cookies. Session cookies only live in the browser's memory, and are not stored anywhere. Persistent cookies, however, are stored on the browser's hard drive. This can cause security and privacy issues depending on the information stored in the cookie and how it is accessed. 
Penetration tests may raise alert about persistent cookies with "expires=" tag.

Feedback from Sustained Engineering department: This is a false positive! Cookies marked as persistent does not contain any confidential nor information which could be abused for attacking QV session management implementation.
