Sharing Session State in ASP.Net
I needed to share session state in an application and was able to accomplish this using SQL Session State, and the tutorial I found here:
http://www.codeproject.com/Purgatory/Sharing_session_state.asp .
I recently conversed with someone that told me he was able to share session state in process by adding this to the web.config:
<system.web><httpCookies domain="Domain.com" httpOnlyCookies="true"/></system.web>
Hope it helps!
