An Application server is a server program that resides in the server (computer) and provides the buiness logic for the application programme. The server can be a part of the network, more precisly the part of the distributed network. The server program is a program that provides its services to the client program that resides either in the same computer or on another computer connected through the network.

The Application server syncs / combines with the web server for processing the request made by the client. If we look at the request-response flow between client, web server and application server, we come to know that the client's request first goes to the web server which sends the required information to the application server that sends back the response to the webserver after taking an appropriate action. The webserver futher sends the processed information back to the client. Web server use different approaches or technology for forwarding or receiving back processed information.
