According to OWASP OFBiz Web Content Caching is weak:
Even after the session has been closed, it might be possible to access the private or sensitive data exchanged within the session through the web browser cache. Therefore, web applications must use restrictive cache directives for all the web traffic exchanged through HTTP and HTTPS, such as the Cache-Control and Pragma HTTP headers, and/or equivalent META tags on all or (at least) sensitive web pages.
Independently of the cache policy defined by the web application, if caching web application contents is allowed, the session IDs must never be cached, so it is highly recommended to use the Cache-Control: no-cache="Set-Cookie, Set-Cookie2" directive, to allow web clients to cache everything except the session ID (see here).
I though noticed that Set-Cookie2 is deprecated for a long time now. And the new browsers policies it to often updated. So no need to use Set-Cookie2.
