The Web forms model is the active server page development and deployment model for .NET. Web forms are for browser-based .NET clients. In this model, an Internet Information Services (IIS) server is responsible for the generation and delivery of the browser-based client code. Your Open Client proxy objects fully support a Web forms model, as long as the Progress.o4glrt.dll and Progress.Messages.dll assemblies, the message resource files, and your proxies are accessible to the server-side code for your Web forms.
