SharePoint - Is it possible to capture sharepoint sign out session id?

Hi,

Is it possible to capture SharePoint Portal Sign out ?
i want to capture the session id while sign out and insert it into database.
Is it possible to do?
can anyone help me in this issue?

Surprisingly there doesn't seem to be a way to get this information using the SharePoint API. However you could retrieve this information from the IIS logs. I think that doing it this way would be more precise than getting it from AD, because a user can login into a system without ever visiting SharePoint.


Another approach would be to use SharePoint auditing. As far as I know there isn't a specific login audit event, but you could audit when a user reads the SharePoint welcome page. Using SPAuditQuery you can retrieve some details.

Thanks for the reply,
but is it possible to find out the user has logged out from the SharePoint Site?

thanks for the code vickey,
but this code gives the current user right.
but i want to capture user log out event, while logging out i want to capture that session id and insert it into database.
i want to know whether the user logged out from site or not.
while logging out, the session id will time out right. so  i need to check whether the user has logged out or not.
