ServicePointManager.UseNagleAlgorithm Property

Determines whether the Nagle algorithm is used by the service points managed by this ServicePointManager object.

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

'Declaration
Public Shared Property UseNagleAlgorithm As Boolean

Property Value

Type: System.Boolean
true to use the Nagle algorithm; otherwise, false. The default value is true.

The Nagle algorithm is used to reduce network traffic by buffering small packets of data and transmitting them as a single packet. This process is also referred to as "nagling"; it is widely used because it reduces the number of packets transmitted and lowers the overhead per packet.

Changing the value of this property does not affect existing ServicePoint objects. Only new service points created after the change are affected.

The Nagle algorithm is fully described in IETF RFC 896.

The following code example sets this property.

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