Thank you for your input. It is much appreciated. I enabled logging in the Server controller and the Exception that we are getting is
Exception message : Session ID is invalid.
Exception class : EInvalidAppID
I know this error usually happens when a session has expired. However, I suspect this is not the case here as there are way too many session ID Invalid error messages in a short time frame in respect to the number of users.
I suspect the application session ids are being dropped or being lost somehow but I am not sure what would be causing it. Some question I have though.
1.Can Server bandwidth or other Server constraints (ISAPI requests/counts) affect the performance of the application such as sessions being dropped or slow performance?
2. Can the error message "session is invalid" be caused by the load balancer not redirecting the request to the Server(where the session was established) which the first request originated from? (ie there is no active session on the other application servers). There are multiple application servers on which the application is being run on. The load balancer directs traffic to a certain application server in which a session is established and subsequent requests should be redirected to the Server where the session was established.
A couple of questions on scaling up and performance tuning
1. what is the maximum number of client connections or sessions can Intraweb Handle?
2. Can the application handle high volumes of users on a single IIS Server with a single application pool and Website?
3. Is it recommended to have multiple application pools and Websites on the single IIS Server ?(ie to distribute traffic on different ports within the same application server)
4. are there any IIS configurations that can better the performance for the Intraweb Application
5. is there any documentation or recommendation when scaling up or performance tuning the Intraweb Application?
