// When a web browser control is created, the net session count is incremented. When the control
// is destroyed, the net session count is decremented. When the net session count reaches zero,
// the session cookies for the process are cleared. SetQueryNetSessionCount can be used to prevent
// the session cookies from being cleared for applications where web browser controls are being created
// and destroyed throughout the lifetime of the application. (Because the application lives longer than
// a given instance, session cookies must be retained for a longer periods of time.
