What is a problem, session ID appended to URLs for clients that do not accept cookie, something like?page=20&SID=dsffsfsdfsdfdsfdsfds
Since that SID will be different for every robot session, your site will not be indexed at all.
A OSC contribution "SID killer" makes sure no session is started for clients do not accepting cookie before it really needs to be (like product in a cart).
