We are closing in on May 18:th now. We have got plenty of good input. To summarize, I have made a preliminary change log, covering things that has been discussed this far. I will also mention ideas that we do not intend to incorporate in this document. If you have suggested something that is not in the list below I may have missed that, please send a reminder to me in such case. If you disagree with something in the list or have other ideas, please let me know. *** Intended changes *** 1.1, Section 4: Clearly mention that IPv6-addresses must be quoted. Also show this in examples. This also applies to IPv4 addresses when the port is specified. 1.2, Section 4: Have a less complex example. Also, make sure that the quote is placed on the right side of the "=". 1.3, Section 4: Add a note that a proxy can also add a new "Forwarded: .."-line, as this is equivalent. 1.4, Section 5.*: Remove some MAY-references. 1.5, Section 5.1: Add a note that the by-parameter may be useful in a multi-homed environment. 1.6, Section 5.2: Add a note that in some situations it is more relevant to read the address of the last proxy in the last Forwarded-by-field. 1.7, Section 5.2: Formulate paragraph 1 to include that the information is not only regarding the initiating client. Also change "user agent" to "client". 1.8, Section 5.5: Change the requirement to notify IANA into: >"It is possible to register additional parameters using the IANA >registration policy described in [RFC3864]" 1.9, Section 6: Require obfport to start with an underscore. 1.10, Section 6 & 6.3: Include "[:._-]" as valid characters in obfnode and obfport. 1.11, Section 6.1: s/zero compression/compression of zeroes/ 1.12, Section 6.1: s/IPv6 adress/IPv6 address/ 1.13, Section 7: Add some notes on when the header should be preserved or not. Duscussed under #7: http://www.ietf.org/mail-archive/web/apps-discuss/current/msg05535.html 1.14, Section 7: Note that this header field is not possible to combine with the information from the via-header field with certainty. 1.15, Section 7.1: Remove the word "correctly" from: "[...] information might not be correctly updated [...]" 1.16, Section 7.x: Encourage proxies to convert X-Forwarded-* when possible. 1.17, Section 8.2: Add the text W. Tarreau mentions: (with the change of must -> should in the first sentence) > This header field should never be copied into response messages by > origin servers or intermediaries for whatever reason as it can reveal > the whole proxy chain to the client. As a side effect, special care > must be taken in hosting environments not to allow the TRACE request > where the Forwarded field is used, as it would appear in the body of > the response message. 1.18, Section 8: Add a section or a note about privacy considerations. *** Suggestions we intend NOT to incorporate *** (somewhat incomplete) 2.1, TCP-options. This can be standardized in a separate document. 2.2, Complex transition schemes. Best regards, Andreas Petersson
