I am trying to use a ZuulFilter in a simple spring-cloud-Netflix Api gateway (reverse proxy) in order to authenticate requests against a custom authentication provider (via Rest call).
The Filter should reject unauthorized requests with a 401 and don't pass those requests further down to the proxied services.
Is that even possible for a ZuulFilter? I did not find documentation, example or something in Zuuls api.
Any suggestions?
I got this to work, took some digging. Make sure your request isn't cached already. Just call this method from your run() method inside your ZuulFilter.
