// Set the maximum number of ServicePoint instances to 
// maintain. If a ServicePoint instance for that host already

// an Internet resource, the ServicePointManager object
// returns this existing ServicePoint instance. If none exists 
// for that host, it creates a new ServicePoint instance.
ServicePointManager::MaxServicePoints = 4;

// Set the maximum idle time of a ServicePoint instance to 10 seconds.
// After the idle time expires, the ServicePoint object is eligible for
// garbage collection and cannot be used by the ServicePointManager.

Poznámky

Když snížíte MaxServicePoints vlastnost pod počet ServicePoint objektů, které aktuálně existují, ServicePointManager odstraní ServicePoint objekty s nejdelší dobou nečinnosti. Pokud je počet ServicePoint objektů s aktivními připojeními větší než hodnota objektu MaxServicePointsServicePointManager , objekt odstraní objekty, jakmile ServicePoint se stanou nečinnými.
