CORS (Cross-Origin Resource Sharing) Configuration
The concept name was not provided, but based on the sources, this entry covers Cross-Origin Resource Sharing (CORS) configuration in SAP API Management. CORS is a browser security mechanism that controls how web applications hosted on one domain can request resources from another domain, and developers configure it in SAP API Management to permit or restrict such cross-origin requests. Using entities such as CrossOriginResourceSharing, CORSAllowedHeaders, and CORSExposedHeaders, developers can define which hostnames, request headers, and response headers are permitted in cross-origin interactions. This allows API developers to avoid CORS-related browser errors when integrating front-end applications with back-end APIs managed on SAP Business Technology Platform.

Prerequisites
- Concept Cross-Origin Resource Sharing (CORS) Cross-Origin Resource Sharing (CORS) is a browser security mechanism that controls how web applications running at one origin can request resources from a different origin, enforcing the [same-origin policy](https://ui5.sap.com/#/topic/672301f4f47640a8b2bc817d2ce0f512). ABAP and SAPUI5 developers encounter CORS when a request from a web front-end is blocked because the target server has not explicitly permitted cross-origin access. [Server security configuration in SAPUI5](https://ui5.sap.com/#/topic/91f3cac16f4d1014b6dd926db0e91070) covers CORS alongside related topics such as clickjacking protection, and developers must ensure the appropriate server-side headers or allowlist entries are in place to allow legitimate cross-origin requests to succeed.
- Concept API Management and Creation The provided sources do not contain sufficient information to define the concept "undefined." The sources cover topics such as migrating from SAP Process Integration/Orchestration to SAP Integration Suite, consuming an API Management Service Instance from Kyma, and creating an API Provider System, but none of them describe or explain a concept identified as "undefined."
- Concept API Policy Configuration and Rate Limiting The concept name was not provided (received "undefined"), so a grounded definition cannot be written. Please supply a valid SAP developer concept name so that a definition can be produced from the available source snippets.
