Designing realistic behaving users involves designing users whose behavior depends on the server responses, and act accordingly. This post explores in details various JMeter While usages and explains them thoroughly. Difference with If Controller The difference is pretty simple to understand: If controller children are executed zero or one time when the condition is met, While controller children are executed zero, one or multiples times depending how many times the condition is met.
