Borland Delphi is known to be a great environment for the development of stand-alone and client-server applications on the Microsoft Windows platform. Its virtues range from full OOP support to visual development, in a unique combination of power and ease. However, the new frontier of development is now Internet programming. What has Delphi got to offer in this new context? Which are the features you can rely upon to build great Internet applications with Delphi? That’s what this paper intends to reveal. We’ll see that Delphi can be used:
• For direct socket and TCP/IP programming;
• In conjunction with third-party components that implement the most common Internet protocols, on the client or the server side;

You’re no longer just creating an application, but a commercial or a TV show, and the user has his or her hand on the remote. It’s called surfing the Web for a reason. As a developer, you need to be keenly aware of the impact of architectural and implementation decisions on application performance and scalability. With this technology, as we are discovering, we are still dealing with a client/server model.
