Client redirects

When a backend returns a redirect, the default behaviour of KrakenD is to follow the redirection and serve the final content to the user. When this behaviour needs to be prevented and let the end-client follow the redirect itself, then you need to enable the no-redirect plugin.

Client redirect configuration

You can stop KrakenD from following redirections like a 301 with the following configuration, highlighting relevant sections:

{
    "version": 3,
    "plugin": {
        "pattern": ".so",
        "folder": "/opt/krakend/plugins/"
    },
    "endpoints": [
        {
            "endpoint": "/redirect",
            "output_encoding": "no-op",
            "backend": [
                {
                    "url_pattern": "/__debug",
                    "encoding": "no-op",
                    "extra_config": {
                        "plugin/http-client": {
                            "name": "no-redirect"
                        }
                    }
                }
            ]
        }
    ]
}

Important: The only encoding you can use is no-op for both the output_encoding of the endpoint and the encoding of the backend.

There is no additional configuration other than enabling the plugin needed.
