Remarks

The StreamWebSocketControl class provides access to advanced socket control data on a StreamWebSocket object.

A StreamWebSocketControl object is automatically created with the parent StreamWebSocket object. The StreamWebSocket.Control property provides access to the associated StreamWebSocketControl object.

Any changes to the StreamWebSocketControl property values must be set before the StreamWebSocket is connected. As a result if you need to make changes to the NoDelay, OutboundBufferSizeInBytes, ProxyCredential, ServerCredential, or SupportedProtocols properties, then these changes must occur before a successful call to the ConnectAsync method on the StreamWebSocket.

The following example creates a StreamWebSocket, and then demonstrates how to set the StreamWebSocketControl.NoDelay property to false. (Other properties may be set in a similar manner.) After this is done, the app can connect the StreamWebSocket.

using Windows.Networking.Sockets;

StreamWebSocket clientWebSocket = new StreamWebSocket();

// Get the current setting for this option.
// This isn't required, but it shows how to get the current setting.
bool currentSetting = clientWebSocket.Control.NoDelay;

// Set NoDelay to false so that the Nagle algorithm is not disabled.
clientWebSocket.Control.NoDelay = false;

// Now you can call the ConnectAsync method to connect the StreamWebSocket.

#include <winrt/Windows.Networking.Sockets.h>
using namespace winrt;
...
Windows::Networking::Sockets::StreamWebSocket clientWebSocket;

// Get the current setting for this option.
// This isn't required, but it shows how to get the current setting.
bool currentSetting{ clientWebSocket.Control().NoDelay() };

// Set NoDelay to false so that the Nagle algorithm is not disabled.
clientWebSocket.Control().NoDelay(false);

// Now you can call the ConnectAsync method to connect the StreamWebSocket.

using namespace Windows::Networking::Sockets;

StreamWebSocket^ clientWebSocket = ref new StreamWebSocket();

// Get the current setting for this option.
// This isn't required, but it shows how to get the current setting .
bool currentSetting = clientWebSocket->Control->NoDelay;

// Set NoDelay to false so that the Nagle algorithm is not disabled.
clientWebSocket->Control->NoDelay = false;

// Now you can call the ConnectAsync method to connect the StreamWebSocket.

Version history

Windows version	SDK version	Value added
1607	14393	IgnorableServerCertificateErrors
1709	16299	ActualUnsolicitedPongInterval
1709	16299	ClientCertificate
1709	16299	DesiredUnsolicitedPongInterval

Properties

ActualUnsolicitedPongInterval	Allows an app to get the actual unsolicited WebSocket PONG interval.
ClientCertificate	Gets the certificate provided by the client when a secure WebSocket connection has been established.
DesiredUnsolicitedPongInterval	Allows an app to get and set the desired unsolicited WebSocket PONG interval.
IgnorableServerCertificateErrors	Gets a list of ignorable server certificate errors. Get this list and add ChainValidationResult values for server certificate errors that you wish to ignore during the secure WebSocket (wss:// protocol) server certificate validation process.
NoDelay	A value that indicates whether the Nagle algorithm is used on a StreamWebSocket object.
OutboundBufferSizeInBytes	The size, in bytes, of the send buffer to be used for sending data on a StreamWebSocket object.
ProxyCredential	The credential to use to authenticate to the proxy server through HTTP header authentication using a StreamWebSocket object.
ServerCredential	The credential to use to authenticate to the WebSocket server through HTTP header authentication using a StreamWebSocket object.
SupportedProtocols	Gets a collection that can be used to add a list of supported sub-protocols that will be advertised to the server during the connect handshake.
