@purekeeper Currently, you may support this by the serverless plugin: https://apisix.apache.org/docs/apisix/plugins/serverless.

- If the header was on request, `proxy-rewrite` plugin is a better choice.
- If it's on response, `response-rewrite` plugin is a better choice.
But both them have no support .
Support to set header if nonexistent, they'll easier to reach intention than `serverless` plugin.

Another compromise is to use the `vars` on the route to distinguish between routes with a specified header and those without one, and to handle them separately.
IMO, don't override if it exists: this will cause to check the all headers, which is inefficient.

Maybe, we can add a configuration to determine if headers needs to be rewritten
