# Client and Server Standards

The paragraphs below describes W3Schools' vision about future Internet Distributed Applications.

## Executables, C++ (and Java too) must die

Neither C++ nor Java can ever create standard components that can run on all computers. There is no room for these languages in future distributed applications. Executables are not standard. COM objects are not standard, DLL-files are not standard. Registry settings are not standard. INI-files are not standard. None of these components must be allowed to destroy your dream of a standard distributed application that will run on almost any computer in the world.

## Clients must be Standard Internet Browsers

Application clients must be standard clients without any additional components. No part of the applications must be stored on client computers. The application must never use, or rely on, any components, dll- or ini-files, registry settings or any other non standard settings or files stored on the client computer. (Then you can start calling it a Thin Client). Our best suggestion is to let all clients use standard Internet browsers like Internet Explorer, Netscape, or Firefox running on Windows or Mac computers.

## Servers must be Standard Internet Servers

Application servers must be standard Internet servers running standard software without any additional components. The application must never use, or rely on, any components, dll- or ini-files, registry settings or any other non standard settings or files stored on the server. Our best suggestion is to use a standard Internet server like Internet Information Services (IIS), with a standard request-handler like Active Server Pages (ASP), and a standard database connector like Active Data Objects (ADO). As your data-store you should use a standard SQL based database like Oracle or Microsoft's SQL Server.

## Applications must use Internet Communication

Application clients and servers must not be allowed to communicate via any proprietary protocol. Clients must request servers via a standard Internet protocol and servers must respond via the same protocol. Clients must be able to use any service without having to maintain a permanent connection to the server. Our best suggestion is to let servers be requested with standard stateless Internet HTTP requests. Servers should respond with a standard stateless Internet HTTP response.
