Affects: 6.0.12
Spring could improve the documentation (both reference and Javadoc) around X-Forwarded-* headers. In particular, the X-Forwarded-Prefix header could use some clarifications as demonstrated in https://github.com/spring-projects/spring-framework/issues/31241
I've discussed this with @rstoyanchev and I'm happy to send a PR with my comment as a starting point for the updated documentation.
