HttpWebRequest.ConnectionGroupName HttpWebRequest.ConnectionGroupName HttpWebRequest.ConnectionGroupName HttpWebRequest.ConnectionGroupName Property

Definition

Gets or sets the name of the connection group for the request.

public:
 virtual property System::String ^ ConnectionGroupName { System::String ^ get(); void set(System::String ^ value); };
[get: System.Runtime.TargetedPatchingOptOut("Performance critical to inline this type of method across NGen image boundaries")]
[set: System.Runtime.TargetedPatchingOptOut("Performance critical to inline this type of method across NGen image boundaries")]
public override string ConnectionGroupName { get; set; }
member this.ConnectionGroupName : string with get, set
Public Overrides Property ConnectionGroupName As String
Property Value

The name of the connection group for this request. The default value is null.

Examples

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.
SHA1Managed^ Sha1 = gcnew SHA1Managed;
array<Byte>^updHash = Sha1->ComputeHash( Encoding::UTF8->GetBytes( "usernamepassworddomain" ) );
String^ secureGroupName = Encoding::Default->GetString( updHash );

// Create a request for a specific URL.
WebRequest^ myWebRequest = WebRequest::Create( "http://www.contoso.com" );

// Set the authentication credentials for the request.      
myWebRequest->Credentials = gcnew NetworkCredential( "username","password","domain" );
myWebRequest->ConnectionGroupName = secureGroupName;

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

// Insert the code that uses myWebResponse here.
// Close the response.
myWebResponse->Close();
// Create a secure group name.
SHA1Managed Sha1 = new SHA1Managed();
Byte[] updHash = Sha1.ComputeHash(Encoding.UTF8.GetBytes("username" + "password" +  "domain"));
String secureGroupName = Encoding.Default.GetString(updHash);

// Create a request for a specific URL.
WebRequest myWebRequest=WebRequest.Create("http://www.contoso.com");

// Set the authentication credentials for the request.      
myWebRequest.Credentials = new NetworkCredential("username", "password", "domain"); 
myWebRequest.ConnectionGroupName = secureGroupName;

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

// Insert the code that uses myWebResponse here.

// Close the response.
myWebResponse.Close();
    
' 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("http://www.contoso.com")
   
' 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.
myWebResponse.Close()
   

Remarks

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 Inheritors

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