The following errata report has been submitted for RFC7230,
"Hypertext Transfer Protocol (HTTP/1.1): Message Syntax and Routing".

You may review the report below and at:

Type: Technical
Reported by: Tim Düsterhus <duesterhus@woltlab.com>

Section: 3.2

Original Text
     field-content  = field-vchar [ 1*( SP / HTAB ) field-vchar ]

Corrected Text
     field-content  = field-vchar [ 1*( SP / HTAB / field-vchar ) field-vchar ]

The ABNF currently rejects "1 2 3" as a valid header value, as the field-content production either matches a single character or two characters separated by whitespace. Thus it consumes the "1 2", leaving "<space>3" which does not match field-value.

This error is already fixed in https://httpwg.org/http-core/draft-ietf-httpbis-semantics-latest.html#rfc.section.5.5

This erratum is currently posted as "Reported". If necessary, please
