Hey @SoufianLabed, thank you for contributing this PR! 🙏

We've just added full Proxy Support for OPAL, including for the Data Fetcher, Policy Engine and the OPAL Client <-> Server WebSocket connection. Checkout the tutorial for OPAL behind a Proxy

With this setup, it resolves the underlying requirement of this PR, making it obsolete. For that reason, I'll close this PR.

I'll invite you to join the OPAL Community over at Slack to continue the discussions and announcements 💎
