I've posted a code of Configuration class for Session Data Management Tool created by Xiangyang Liu to store data between different threads in ASP.NET asyncronous application.
The source code of the tool has SessionService web site where configuration is done in global.asax.
To make it easier to incorporate it into existing ASP.Net web application, it was moved to a separate class. The changes also were done to store trace and data folders in Temp directory, which is easier for deployment.
