RFC 7239, "Forwarded HTTP Extension", June 2014Source of RFC: appsawg (app)
Errata ID: 5275
Publication Format(s) : TEXT
Reported By: W. Trevor King

Section 4 says:
Forwarded = 1#forwarded-element
It should say:
Forwarded = forwarded-element *(OWS "," OWS forwarded-element) OWS = <Defined in [RFC7230], Section 3.2.3>
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.
