HttpWebRequest.ConnectionGroupName Property

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

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

public override string ConnectionGroupName { get; set; }
/** @property */
public String get_ConnectionGroupName ()

/** @property */
public void set_ConnectionGroupName (String value)

public override function get ConnectionGroupName () : String

public override function set ConnectionGroupName (value : String)

Not applicable.

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.
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.
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("http://www.contoso.com");

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

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

// Insert the code that uses myWebResponse here.
// Close the response.
myWebResponse.Close();

//Create a WebRequest
var wReq : WebRequest = WebRequest.Create("http://www.contoso.com/")
       
// 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.
wResp.Close()
