Description

The new NN UI shows links to DN web pages, but since the link is from the info address returned from jmx, it is in the IP address:port form. This breaks if users are using filters utilizing cookies.

Since this is a new feature in 2.8, I didn't mark it as a blocker. I.e. it does not break any existing functions. It just doesn't work properly in certain environments.
