Description

I'm trying to use a lua HTTP filter to set a response header whose value depends on a request header.

As a simple example, suppose we want to copy a header from the request to the response. How can we do this using a lua filter?

Maybe we can store the request header in a "global" table during envoy_on_request and read it later when envoy_on_response is called. However, even if this approach makes sense, how can we correlate responses with requests to be able to do this?
