BrowserStart Function

Action

BrowserStart is used to start the browser and also to manage virtual user behavior. There are two types of VUsers: Revisiting users and first time users. For first time users, the browser state (cookies, cache, and history) is cleared on each call to BrowserStart. Revisiting users reuse persistent session information.

注: BrowserReset also resets the browser state.
