some of those were spoofable, weren't they?
read the right most value
railway is not going to be using envoy forever
ok, true, but there was a problem with clients being able to just set arbitrary value to
X-Forwarded-For^
I didn't see any updates that it was fixed
bruh
it should be overwritten, not appended
anyway, I'm out then
so uh
it can be spoofed
^
i'd say the right one is X-Forwarded-For
i just need the remote ip
read the right most value from that header and you will get the remote ip
ok thanks
it works, thank you
no problem
