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.
