Description

Currently, Akka HTTP doesn't support the standard header Forwarded, but only one of the de-facto standard X-Forwarded-For header that is only part of the standard Forwarded.

It would be good to add support for Forwarded header as described in https://tools.ietf.org/html/rfc7239

Additionally, it might be also good to implement X-Forwarded-Proto and X-Forwarded-Host:

Headers added

  • X-Forwarded-Proto and X-Forwarded-Host
  • Forwarded

Contributor guide

Research direction
Study RFC 7239 for Forwarded header syntax, then implement a model parser and renderer similar to existing X Forwarded For in akka http. Add header class, parsing logic, and tests.
