In a given scenario under IBM Rational Performance Tester, assume that the token ID’s and User session ID’s are present in the request as dynamic values. These values would thereby be present throughout the requests in the script.
Once the script is recorded, The transactions are segregated where the login and logout are placed outside the loop and remaining transactions are placed within a loop, which are run for multiple iterations.
Sometimes, these dynamic values present within the loop might not get addressed by the server correctly . Response content got from the server could appear blank. This happens as the server expects the sessions to be different. However in this case it would be that the same dynamic content is being passed in the requests and the server does not acknowledge with a response.
This could be addressed by placing the login and logout transactions within the loop. Doing so, the logout removes the old dynamic values and login creates new value.
