Hi all, I'm really new to Nginx and I'm going to study many of its useful options and modules...

I would to ask a question about an interesting scenario:

- A user needs to contact a service behind a WAF
- When the request arrive to the WAF, this one encrypt the IP address on the header and generates a key
- The packet arrive to the nginx engine
- The engine must use the key to decrypt the IP address and save It on a log.

That's It for the moment, I'm searchng around about the best methos to solve this scenario and first of all I would like to understand If this is possible using Nginx OR It's necessary to have Nginx Plus.

Thank you very much for your answers.
