This directly references SymfonyDocs #6197, where I originally posted it by mistake.

In this section, the documentation states:

By default, the following proxy headers are trusted:

X-Forwarded-For Used in getClientIp();
X-Forwarded-Host Used in getHost();
X-Forwarded-Port Used in getPort();
X-Forwarded-Proto Used in getScheme() and isSecure();

I want to make clear that I'm not a proxy expert, but as I understand it, those headers are not standard. They're common (pseudo-standard) but not standard since the RFC 7239 was released in 2014

My points are:

1. Does it support the standard Forwarded header by default and all its attributes? This is an actual question, as I can't try it right now. If not, it should. Because standards. Standards are cool.
2. In the same line, I put up to debate if it should support the pseudo-standard headers by default. Is it useful? Yes, it is; but it can be argued that it fights against the extension of the standard, which I think is a burden mid-long term, because people (especially devs, especially me) are lazy and standards are cool and dandy but the path of least resistance is even cooler; and when the standard is not the path of least resistence for the majority, the very concept of standard becomes useless... and that makes me sad 😢

TL;DR; You're not gonna read it? Then you're either a _a)_lazy or a _b)_busy person. Case a)C'mon, I made it fun and easy to read. Case b) I will probably waste your time. This is not the urgent issue you're looking for
