Internet Explorer + Subdomains

[eluser]Unknown[/eluser]
I need to use different sessions on subdomains of site (for social apps).

All browsers use different sessions for subdomains, but IE use the same. If I log in in Application, then in another tab with normal site i have the same data. But i different. What I can do to split sessions for domain and subdomains in Internet Explorer?


P.S. CodeIgniter + Native-sessions class (with standart session class was same problem).
