How Integration Server Handles CORS Requests
Configuring Integration Server to Accept CORS Requests
CORS (Cross-Origin Resource Sharing) is a specification that provides the standards for user agents (such as web browsers) to allow client-side web applications running in one origin to access resources from another origin. For security reasons, cross-origin requests initiated by scripts are usually restricted by user agents; however, user agents can use CORS to allow and define these cross-origin communications.
