Query re "what cookies does community use"

In the page re which cookies the community uses it mentions the blog post list widget and the filtering as per thread posts but the blog post widget doesn't appear to have this functionality or create any cookies?

What cookies does Community use?

Telligent.Evolution-UI

Default cookie used for storing values from widgets. This stores the user's view preferences for blog post lists and forum thread lists.
Can be disabled via widget code (BlogPostList and ForumThreadList)


Does this need to be updated or am I missing where the cookies are used ? 

Also for saas sites is there a list of cookies used by the waf as we are seeing some new cookies which appear to be linked to this, I am happy if this can be shared privately
