Difference with regenerateExpiredSessionId="false" and regenerateExpiredSessionId="true" .net

Question

My understanding from

http://msdn.microsoft.com/en-us/library/system.web.configuration.sessionstatesection.regenerateexpiredsessionid.aspx

meaning of regenerateExpiredSessionId="false" was that if a session id expired it will NOT be re used if client requests an url with same id.

And mening of regenerateExpiredSessionId="true" was that if a session id expired it will be re-used (recycled) if client request an url with same id.

But when i read post at

http://stackoverflow.com/questions/392272/regenerateexpiredsessionid-not-working-as-expected

it seems that i misunderstood what regenerateExpiredSessionId="true" means.

Can some one explain which is right?

I believe that the word "reissue" is problematic when people discuss this attribute. I have seen some posts interpret it to mean "a new session id is generated and issued to the client," and others which interpret it to mean "an expired session id is assigned to a new session and issued to the client." I believe that the msdn documentation means it in the latter sense, and that the stack overflow post you reference incorrectly interpreted it as the former.
