Once Only Controller

If we wish that a particular request executes only once per thread group,we need to use "Once Only Controller". All the requests  grouped under the controller will run once although you might have mentioned loop count more than 1.Below is an example

Since loop count is 2,All three request should have run twice but  "Login to Facebook" request will execute only once since this has been placed under "Once only Controller"




In View Result Tree,"Login to Facebook" request runs for once although other two requests executed twice
