In section 14.3, the definition of Accept-Encoding is given as follows:
Accept-Encoding = "Accept-Encoding" ":" 1#( codings [ ";" "q" "=" qvalue ] )
This definition implies that there must be at least one non-null codings. However, just below this definition, one of the examples given has an empty Accept-Encoding field-value:
Accept-Encoding: compress, gzip
Accept-Encoding:
Accept-Encoding: *
Accept-Encoding: compress;q=0.5, gzip;q=1.0
Accept-Encoding: gzip;q=1.0, identity; q=0.5, *;q=0
Furthermore, the fourth rule for testing whether a content-coding is acceptable mentions the possibility that the field-value may be empty.
The definition for Accept-Encoding should be revised:
Accept-Encoding = "Accept-Encoding" ":" #( codings [ ";" "q" "=" qvalue ] )
Resolving as per < http://greenbytes.de/tech/webdav/draft-lafon-rfc2616bis-04.html#rfc.issue.i25-accept-encoding-bnf > and < http://www.w3.org/2007/03/18-rfc2616-minutes.html#action09 >.
