What role does the Pega Composite Gateway serve in IAC?

The Pega Composite Gateway serves as a servlet for proxying HTTP communication in Integrated Application Composite (IAC) scenarios. Its primary function is to facilitate communication between different applications and services by managing the exchange of HTTP requests and responses. This is crucial for ensuring seamless integration and interoperability between Pega applications and other external systems, as IAC often involves the use of multiple applications that need to communicate efficiently.

The gateway plays a pivotal role in handling incoming requests, processing them, and then routing them appropriately to the designated services or applications. This includes managing session state and enabling various HTTP methods to ensure that different types of interactions can occur between applications.

Understanding the Pega Composite Gateway's role in IAC is essential for effectively designing and implementing applications that utilize multiple integrated components, ensuring that they work together smoothly and reliably.
