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

 static property int DefaultConnectionLimit { int get(); void set(int value); };
public static int DefaultConnectionLimit { get; set; }
static member DefaultConnectionLimit : int with get, set
Public Shared Property DefaultConnectionLimit As Integer

Property Value

Int32

The maximum number of concurrent connections allowed by a ServicePoint object. The default connection limit is 10 for ASP.NET hosted applications and 2 for all others. When an app is running as an ASP.NET host, it is not possible to alter the value of this property through the config file if the autoConfig property is set to true. However, you can change the value programmatically when the autoConfig property is true. Set your preferred value once, when the AppDomain loads.

Exceptions

ArgumentOutOfRangeException

DefaultConnectionLimit is less than or equal to 0.

Examples

The following code example sets this property.

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;

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

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.
