Release 10.1A: OpenEdge Getting Started:
WebSpeed Essentials

> ## Introducing WebSpeed

> WebSpeed® is a Progress® 4GL development and deployment environment. WebSpeed allows you to build applications that use HTML, XML, WML, DHTML, and most other mark-up languages (MLs) as the user interface. This means that WebSpeed can be used for applications where users are accessing the application using:

> - A Web browser (HTML, DHTML, or XML).

> - A mobile/cell-phone (HTML, WML).

> - A system making requests for information using XML and HTTP or HTTP/S as the transport protocol.

> In addition to building Web-based applications by design, you can use WebSpeed to Web-enable existing OpenEdge applications that previously ran stand-alone or as a Progress AppServer™-based application.

> With WebSpeed, you can develop and deploy:

> - Intranet applications that allow internal users to access and modify data.

> - Internet applications that allow external, consumer access (for example, a shopping cart application).

> - Extranet, business-to-business applications.

> This chapter covers the following topics:

> - WebSpeed architecture

> - WebSpeed request round-trip

> - Web programming and WebSpeed

> - WebSpeed and the OpenEdge platform
