ServicePointManager.DefaultConnectionLimit ServicePointManager.DefaultConnectionLimit ServicePointManager.DefaultConnectionLimit ServicePointManager.DefaultConnectionLimit Property


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; }
member this.DefaultConnectionLimit : int with get, set
Public Shared Property DefaultConnectionLimit As Integer
Property Value

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



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 = _


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.


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.
