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)

static member DefaultConnectionLimit : int with get, set

Property Value

Type: System.Int32
The maximum number of concurrent connections allowed by a ServicePoint object. The default value is 2.

ExceptionCondition
ArgumentOutOfRangeException

DefaultConnectionLimit is less than or equal to 0.

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.

NoteNote

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.

The following code example sets this property.
