Internet applications can be classified broadly into two kinds: client applications that request information, and server applications that respond to information requests from clients. The classic Internet client-server application is the World Wide Web, where people use browsers to access documents and other data stored on Web servers worldwide.
Applications are not limited to just one of these roles; for instance, the familiar middle-tier application server responds to requests from clients by requesting data from another server, in which case it is acting as both a server and a client.
The client application makes a request by identifying the requested Internet resource and the communication protocol to use for the request and response. If necessary, the client also provides any additional data required to complete the request, such as proxy location or authentication information (user name, password, and so on). Once the request is formed, the request can be sent to the server.
