Hello everybody!! I meat with a problem of indexing site by Google. It is a matter of common knowledge that Googlebot doesn't use any cookies thus when visiting the the site it will get not the short url like we got used to see in our browsers (with cookies turned on) but with the long session ID (i.e. http://ideal-k.com.ua/(X(1)A(39SR9jT...ookieSupport=1) . And each time the Googlebot visits the site it will get a new session ID. The biggest problem such url leads is that google identifies these urls like DIFFERENT pages and can reduce the page rank because of "contents duplicating". I tried to set the page directive (EnableSessionState = "False") for the default.aspx and tested on the cookieless browser - same reaction as before - the session ID was present in url. The master page doesn't have such directive compile directive at all. That led me to the last chance - to disable Session state in web.config: <sessionState mode="Off"/> . Imagine how big was my surprise when I also didn' see any change of the ASP.Net: session ID still was present. Does anybody know where is my mistake?

The reason you can't get rid of this "Session ID" is because what you are seeing here is not a SessionID at all.

Rather, it is an identifier used for anonymous identification. You can tell by the X(1)A part at the beginning. Session IDs start with X(1)S.

You have this because you have set the cookieless attribute of <anonymousIdentification> to either "AutoDetect" or "UseUri".

<anonymousIdentificationcookieless="AutoDetect"enabled="true"/>

Set it to "UseCookies" to get rid of the X(1)A identifier in the querystring. Better yet, if you don't need to have anonymous identification, disable it altogether.
