Session Based Blog System

Hi
I am looking for a open source Blog system which I can implement on my

site.

I found quite a number of them but the issue is that all the ones that I

found use a cookie based approach i.e. for the users of the site need to

have Cookies enabled in their browsers for the Blogs to function.

I was wondering if there is a open source Blog system which is Session

Variable based without the use of client side cookies so that even if the

users have Cookies disabled in their browsers the Blog would work for

them

Does anyone know of a open source Blog system that is Session based??

Thanks
P
