How can we know in advance the hash/hmac value ?

Hi there,

For my project, I need to know the Cookie values before sending any requests to nginx. It works if I use the "hash=index" because I know how many servers I got and the specific order, however, I would like to use the other hashes.

By looking a bit into the code, it seems all kind of hashes are a hash of the IP+Port (sockaddr); and it is an issue for me because the server could change its IP without notice, or having a different IP depending the DNS location.

So, I was wondering if it was possible (or better?) to hash the string from "server xxx;" definition instead of using a runtime property.

I would like to have your feedbacks on that, if possible.

Thank you in advance,
