# Controlling Application Flow

One of the primary choices of any application design is the pattern of execution. In a well-designed application, the logic of converting inputs to outputs by using modular processing units is obvious. The COM architecture and Active Server Pages (ASP) address this need for modular design to control the flow of execution in the Windows DNA architecture.

This section outlines some of the more important issues to keep in mind when designing how you will control the flow of your Web application. The topics included are:

- Application Control Techniques: Describes the different ways to affect the general flow of execution.
- Coordinating Client/Server Processing: Outlines the design goals when you distribute processing between the client and server.
