For example :
I have two Virtual user profile and I have login and logout container which is common to the two Virtual user.
So I will put this login and logout in Shared container.
While executing the two Virtual user profile. Do the script execute with the login and logout container which i have copied in shared container ??? or what???
When you put your Login and Logout as shared container, this means that all the users that are using those shared containers will execute exactly the same transactions.
You can see a shared container like a shortcut that you can use on different virtual user. So your two virtual user profile will execute the same Login/Logout containers.
