Hi, Can you give context to the change?

Why do you need goproxy as a reverse proxy?

aplulu commented 4 months ago

Hi, I apologize for any confusion caused by accidentally opening a Pull Request against the upstream repository instead of my forked repository. That was an unintended mistake on my part.

To provide some context, the purpose of using goproxy as a reverse proxy in this case is to facilitate the integration of Autify, an E2E testing service, with an environment protected by Google Cloud's Identity-Aware Proxy (IAP). The goal is to inject authentication information into the requests using the proxy created with goproxy, enabling the E2E tests to be conducted in the IAP-protected environment. In order to achieve this, it is necessary to send the Proxy-Authorization header to the Google Cloud Load Balancer. Additionally, I wanted to ensure that the header is not removed even in the case of connections over HTTPS.
