Deactivated cookies in browser

In the case a browser does not allow cookies I have edit the following changes in the web.config file:
<forms ..... cookieless="AutoDetect" .......   (or better cookieless="UseDeviceProfile" ? )
But in both cases it does not work and I get an error. The generated url looks quite good, I think:
http://localhost:49695/BlogEngine/(X(1)F(aZkij24rlPLUQsflWqgwcezhuzQupaj-R6ISpptPZ7ggUKlrqkaoy5MuM1ih0dRTCm2EJ4HaQ-3PvvEJhuEz6nt7Z5tVkH0OrMHTTgKR2aY1))/default.aspx
My question: Are there other changes in the web.config file necessary?
I would like to change the sessionstate in the same way:
<pages enableSessionState="true"  cookieless="AutoDetect" ........
