Since the different sever types were introduced I have been using {WebProperty=Server}.

I reviewed the help and Henri's tutorial and now I am second guessing myself.

Should all Server properties be ServerSession?

I am not coming up with a reason to not just always use ServerSession.

I guess I must be missing something fundamental as to why a Server property type even exists?

Can someone enlighten me as to what I am missing for the 2 different types of Server Properities?
