    DedupeResponseHeader GatewayFilter Factory

    +
    +

    The DedupeResponseHeader GatewayFilter Factory takes a name parameter and an optional strategy parameter. name can contain a list of header names, space separated.

    +
    +
    +
    application.yml
    +
    +
    spring:
+  cloud:
+    gateway:
+      routes:
+      - id: dedupe_response_header_route
+        uri: http://example.org
+        filters:
+        - DedupeResponseHeader=Access-Control-Allow-Credentials Access-Control-Allow-Origin
    +
    +
    +
    +

    This will remove duplicate values of Access-Control-Allow-Credentials and Access-Control-Allow-Origin response headers in cases when both the gateway CORS logic and the downstream add them.

    +
    +
    +

    The DedupeResponseHeader filter also accepts an optional strategy parameter. The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE.
