`CORSConfig` maps `AllowedOrigins`, `AllowedHeaders`, and `MaxAge` into `cors.Options`, but doesn't map `ExposedHeaders` even though `rs/cors` supports it. This means there's no way to set `Access-Control-Expose-Headers` through receiver config — anyone who needs it has to write a custom middleware. This came up in jaegertracing/jaeger#8128 where the Jaeger UI needs specific headers exposed over CORS but has to work around this gap with a hand-rolled middleware. ### Changes - Add `ExposedHeaders []string` to `CORSConfig` - Wire it into `cors.Options` in `ToServer()` - Add test - Update README Signed-off-by: Rajneesh Chaudhary <[email protected]>
