Public Overrides Property ConnectionGroupName As String
Dim instance As HttpWebRequest
Dim value As String

value = instance.ConnectionGroupName

instance.ConnectionGroupName = value
/** @property */

public override function set ConnectionGroupName (value : String)

Property Value

The name of the connection group for this request. The default value is a null reference (Nothing in Visual Basic).

The ConnectionGroupName property enables you to associate a request with a connection group. This is useful when your application makes requests to one server for different users, such as a Web site that retrieves customer information from a database server.

Notes to Implementers Each connection group creates additional connections for a server. This may result in exceeding the number of connections set by the ServicePoint.ConnectionLimit property for that server.

The following code example show how to use user information to form a connection group, assuming that the variables username, password, and domain are set by the application before this code is called.

' Create a secure group name.
Dim Sha1 As New SHA1Managed()
Dim updHash As [Byte]() = Sha1.ComputeHash(Encoding.UTF8.GetBytes(("username" + "password" + "domain")))
Dim secureGroupName As [String] = Encoding.Default.GetString(updHash)
' Create a request for a specific URL.
Dim myWebRequest As WebRequest = WebRequest.Create("")
' Set the authentication credentials for the request.      
myWebRequest.Credentials = New NetworkCredential("username", "password", "domain")
myWebRequest.ConnectionGroupName = secureGroupName
' Get the response.
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()
' Insert the code that uses myWebResponse here.
' Close the response.

// Create a secure group name.
SHA1Managed sha1 = new SHA1Managed();
ubyte updHash[] = sha1.ComputeHash(Encoding.get_UTF8().
    GetBytes(("username" + "password" + "domain")));
String secureGroupName = Encoding.get_Default().GetString(updHash);

// Create a request for a specific URL.
WebRequest myWebRequest = WebRequest.Create("");

// Set the authentication credentials for the request.      
myWebRequest.set_Credentials(new NetworkCredential("username", 
    "password", "domain"));

// Get the response.
WebResponse myWebResponse = myWebRequest.GetResponse();

// Insert the code that uses myWebResponse here.
// Close the response.

//Create a WebRequest
var wReq : WebRequest = WebRequest.Create("")
// Set the Authentication credentials for the request.
wReq.Credentials = new NetworkCredential(username, password, domain)
// Assign the request to a connection group based on the user//s name
wReq.ConnectionGroupName = username
//Get the response
var wResp : WebResponse = wReq.GetResponse()

//Use the response and then close.
