Configurable order or weight of headers in the proxy_ip_parser middleware

[stl-victor-sudakov]

There are different situations when for example the “X-Forwarded-For” header cannot be trusted but the "CF-Connecting-IP" can. The list of HTTP headers is however hardcoded in the middleware.

Is it possible to make the order/weight of the parsed headers configurable?

Just wondering if there is such a PR introducing order/weight of headers, does it stand a chance to be accepted, or are there some principal considerations that it should remain fixed?

Hey @stl-victor-sudakov 👋🏻
Yeah, this is a good idea, actually. We don't have a configuration for that middleware (however, it is pluggable, you may remove it and replace with your own), but worth adding.

Are there any recommendations concerning configuring the plugin in the roadrunner config?

[rustatian]

The proxy-ip-parser middleware has only trusted_subnets configuration option. But don't have any preference for the proxy headers. You may fork that middleware, tune, and build your RR binary using Velox or by simply replacing the plugin the in RR's source code (if you know Go).

EDIT: I mean, while waiting for the update.
