It is written in the book about the possibility to use cloaking to disable session IDs in the urls for crawls. (i.e. http://ideal-k.com.ua/(X(1)A(T_4QNS7...ookieSupport=1) They are seen in the browser only in case of Cookies are disabled. But Author didn't draw the way how to do it. The days of googling didn't lead me to any solution. MSDN says that for disabling sesion state of a particular page we must put a compile directive EnableSessionState="False" and disabling for the whole application is done in the web.config <sessionState mode="Off"/> But these two ways are "static" and influence on the ASP site compilation and can't be changed programatically (for people USE session state and for crawls NOT USE). Tried to ask the author by mailing him directly but no answer since weeks. Does anybody know the answer?

One Point is solved: the part of url started with X(1)A is the identifier used for anonymous identification. The solution is described here: Session ID problem But another part of url started with X(1)S - is the session ID. ( http://ideal-k.com.ua/(X(1)S(ysa3k5r...ookieSupport=1 ) The problem remains unsolved.
