Gets or sets the name of the connection group for the request.
Assembly: System (in System.dll)
The 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();
