[edit] X-Forwarded-For vs Client-IP

What's the difference ? —Preceding unsigned comment added by 58.136.73.164 (talk) 02:40, November 3, 2006 (UTC)

[edit] Proxy3?

The "Format" section of this article current says the following:

The general format of the header is:

X-Forwarded-For: client1, proxy1, proxy2

where the value is a comma+space separated list of IP addresses, the left-most being the farthest downstream client, and each successive proxy that passed the request adding the IP address where it received the request from. In this example, the request passed proxy1, proxy2, and proxy3 (proxy3 appears as the client).

But there is no "proxy3" in the example. The numbering implies that the example should read:

X-Forwarded-For: client1, proxy1, proxy2, proxy3

but then the text would seem to be saying that XFF would report the client IP at both the front and back of the chain, which makes no sense. Is this suppose to be saying "proxy3 being the IP that appears to be the client" to some component in this situation, like the end-user application or some network report? If so, the prose should say this, and the example should include the "proxy3". As it is, it makes no sense to someone not versed in XFF, who is the intended audience of the article. (Why would someone who knows XFF need the information?) I'd fix this myself, but I don't know whether this is a technical error or actual confusion of the editors. ~ Jeff Q (talk) 01:06, 25 October 2007 (UTC)

Jeffq: You are right. I had to read this page to interpret what was being said. Re-wording would probably be nice. —Preceding unsigned comment added by 70.235.23.97 (talk) 06:20, 23 December 2007 (UTC)

I did some clarifications to the article text and a note about security considerations, hope you like it. - 83.254.215.235 (talk) 09:45, 19 March 2008 (UTC)
