This article is intended to solve the mutex problem, arising in huge websites, where a lot of information for each session user has to be unique. Here the solution for the mutex problem is done using the ASP web technology. The same logic can be implemented in other technologies also. In fact this solution can even be implemented in client server applications.
In a huge web application thousands of users log-in, and log-out in a hour from all over the world. Now, we some times need to provide them a unique ID instead of just a sessionID, and this cannot be done using any feature in IIS. Say, if we want to give them a unique ID for a table, then it is difficult to use the application.lock method, and then we need some extra mechanism to generate a unique ID. See Global.asa from the downloadable zip for details on how I have implemented the unique ID generation.
