Gets a Boolean value that indicates whether the client requests a persistent connection.

Namespace:  System.Net

member KeepAlive : bool

Property Value

Type: System.Boolean
true if the connection should be kept open; otherwise, false.

If an HTTP client and server expect to exchange data multiple times in a short time period, a persistent connection speeds up their communications by allowing them to avoid the overhead required to open and close a TCP connection for each message. For clients using HTTP/1.1, the default value for this property is true.

The following code example demonstrates using this property.
