Performance testing is iteration process means create script for one real user and run the script for huge or many users. How server identifies the each user actions for multiple users, for this server creates an UNIQUE USER SESSION for every user. Using this session user can perform this actions or transactions. Once user signout from application , once again server creates new session for the same user. So for each user has unique sessions.
We created a script for real one user, so script records the unique session id in the script. If i am running second time script uses the recorded session id due to this script will throw error. So we need to change the dynamic values (like session Id) each user, this is called correlation. In computer science terminology making "constant" value to "variable".
Correlation is capturing the dynamic values from the server then passing that value to the script.
