Why does Magento use 2 cookies per session?

Question

For data security and privacy reasons I want to know why Magento uses two cookies for one frontend session.

All I know is that one of them is being set in Mage_Cor

Answer 1

That is interesting. I just checked on an install of enterprise edition and only "PHPSESSIONID" is set, "frontend" and "admin" are missing even when logged into both. Perhaps this is something still actively being developed.
