HttpWebRequest.ConnectionGroupName Property

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.

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();
