FACT: CodeIgniter's Session Class is NOT RELIABLE.

CI's session class uses cookies. The cookies they write are standards-compliant, but don't work with IE. So, the problem is with CI's refusal to work around IE's non-standards-compliant handling of cookies. Meanwhile, the rest of us have to suffer because of CI's refusal to get off their high horse and make something that works in the REAL WORLD.
