ServicePointManager.DefaultConnectionLimit Property

Gets or sets the maximum number of concurrent connections allowed by a ServicePoint object.

Namespace: System.Net
Assembly: System (in system.dll)

Syntax

Visual Basic (Declaration)

Public Shared Property DefaultConnectionLimit As Integer

Visual Basic (Usage)

Dim value As Integer

value = ServicePointManager.DefaultConnectionLimit

ServicePointManager.DefaultConnectionLimit = value

public static int DefaultConnectionLimit { get; set; }

C++

public:
static property int DefaultConnectionLimit {
    int get ();
    void set (int value);
}

/** @property */
public static int get_DefaultConnectionLimit ()

/** @property */
public static void set_DefaultConnectionLimit (int value)

JScript

public static function get DefaultConnectionLimit () : int

public static function set DefaultConnectionLimit (value : int)

Property Value

The maximum number of concurrent connections allowed by a ServicePoint object. The default value is 2.

Exceptions

Exception type	Condition
ArgumentOutOfRangeException	DefaultConnectionLimit is less than or equal to 0.

Remarks

The DefaultConnectionLimit property sets the default maximum number of concurrent connections that the ServicePointManager object assigns to the ConnectionLimit property when creating ServicePoint objects.

Changing the DefaultConnectionLimit property has no effect on existing ServicePoint objects; it affects only ServicePoint objects that are initialized after the change. If the value of this property has not been set either directly or through configuration, the value defaults to the constant DefaultPersistentConnectionLimit.

Note
Any changes to the DefaultConnectionLimit property affect both HTTP 1.0 and HTTP 1.1 connections. It is not possible to separately alter the connection limit for HTTP 1.0 and HTTP 1.1 protocols. When used in the server environment (ASP.NET) DefaultConnectionLimit defaults to higher number of connections, which is 10.

Example

The following code example sets this property.

Visual Basic

ServicePointManager.UseNagleAlgorithm = True
ServicePointManager.Expect100Continue = True
ServicePointManager.CheckCertificateRevocationList = True
ServicePointManager.DefaultConnectionLimit = _
    ServicePointManager.DefaultPersistentConnectionLimit

ServicePointManager.UseNagleAlgorithm = true;
ServicePointManager.Expect100Continue = true;
ServicePointManager.CheckCertificateRevocationList = true;
ServicePointManager.DefaultConnectionLimit = ServicePointManager.DefaultPersistentConnectionLimit;

C++

ServicePointManager::UseNagleAlgorithm = true;
ServicePointManager::Expect100Continue = true;
ServicePointManager::CheckCertificateRevocationList = true;
ServicePointManager::DefaultConnectionLimit = ServicePointManager::DefaultPersistentConnectionLimit;

ServicePointManager.set_UseNagleAlgorithm(true);
ServicePointManager.set_Expect100Continue(true);
ServicePointManager.set_CheckCertificateRevocationList(true);
ServicePointManager.set_DefaultConnectionLimit(
    ServicePointManager.DefaultPersistentConnectionLimit);
