The following errata report has been submitted for RFC7239,
"Forwarded HTTP Extension".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata/eid5275

--------------------------------------
Type: Technical
Reported by: W. Trevor King <wking@tremily.us>

Section: 4

Original Text
-------------
Forwarded   = 1#forwarded-element


Corrected Text
--------------
Forwarded   = forwarded-element *(OWS "," OWS forwarded-element)
OWS = <Defined in [RFC7230], Section 3.2.3>


Notes
-----
Currently the only mention of commas in the RFC is in the text:

> A proxy server that wants to add a new "Forwarded" header field value can either append it to the last existing "Forwarded" header field after a comma separator or add a new field at the end of the header block.

This should be reflected in the ABNF.  The original ABNF suggests you just smash the forwarded-elements together with no delimiters.

Instructions:
-------------
This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party  
can log in to change the status and edit the report, if necessary.
