Description

We have a request to record the original URL before Envoy rewrites it in an access logging extension. The feature request is to preserve the original headers (or subset of) for the purpose of logging.

Contributor guide

Research direction
Investigate Envoy's access log extension mechanism to understand how to store original headers before rewriting. Look at the current header handling in the filter chain and identify where headers can be captured.
