Overview

Handler to determine real client IP address when Alfodr is behind trusted reverse proxy or proxies, and save it to context.client_ip.

Reverse proxy should pass client IP in a header such as "X-Forwarded-For". In case of multiple values in a header, the leftmost one is used.

For this functionality to not cause security concerns, all trusted, public-facing reverse proxies should delete the header if request is coming from an untrusted client before appending their own, valid value.

Defined in:

alfodr/pipes/client_ip.cr
