Internet Explorer is having problems with my session data

[eluser]KeyStroke[/eluser]
Hi,

In my application, I set session data using the 'set_userdata()' method in the session class, which saves it in the database. However, it seems that Internet Explorer (only) is having problems retreiving data from my session in some parts of my program. Whenever I request something from the session ($this->session->userdata('logged_in') for example), it would return an empty string.

The code seems perfectly fine since it works in all browsers except for Internet Explorer (6&7. Is this a known issue? and how is it solved?
