About Pega Web Mashup

Pega Web Mashup, known as the Internet Application Composer (IAC) in Pega 7.1.7 and earlier versions, enables you to embed an application as a gadget on the pages of a web application located on your intranet, extranet, or internet site. Such an application is called a Pega composite application.

The components and process for Pega Web Mashup

Previous to Pega 7.2.1, Pega Web mashup required the Gateway servlet. Currently, the Pega gadget can run in a different domain or different server and does not need the Gateway servlet.

This article provides an overview of how each part in a Pega Web Mashup implementation works. Additional articles provide configuration instructions, and development tips.
