Asp.net application with more than one workflow

Question

In the IIS application pool, I set 2 to the maximum workflow in the process model, the application object, the session object and the cache object will be shared by the entire workflow or all workflows will have a different application object, session object and cache object.

Answer 1

If you use proc in state management, the session is saved in the running process. Therefore, if you have 2 or more workflows, your session will only work by chance. You can use SQL State Management or State Server. Using the state server is pretty fast, but if the state server goes down or reboots, all sessions will be lost. Using a SQL server is somewhat slower, but it has the advantage that the session will be available after a reboot or any kind of interruption. So the choice depends on your requirements. If you are using an e-commerce site or similar, you can configure a sql server with clustering and multiple web servers to get the best uptime.

As for caching, the same thing is that the cache is stored in the workflow. Depending on how expensive it creates objects in the cache, you can use MemCached or something like that. But then you need to serialize / deseriliaze cache objects and send them over the wire to another server, which can also be quite expensive.
