}
}

after this third request it will give us conflict as it is suppose to becase we are trying to update first request with plugin that already is loaded in newFeature2(second request), but when I check startup config and running config I receive correct answer in startup config with both blugins loaded but running config contains only one of them. Other one is removed out of them.
