Proxying requests based on $http_authorization (API Key)

[justin]

Hello.

We are looking to proxy requests to different backends using upstream based
on http basic auth. I.E. the API key of the request. I am thinking I need to
first get the API key from the raw http request ($http_authorization). Then
do a lookup in redis for the backend to forward too.

We are already using OpenResty. Can we do this natively, or even better yet,
are there 3rd party modules we can utilize to help with this? Is using lua
required, or can we utilize standard nginx directives?

Thanks for the help, and insights.
