Parses the "Range:" header, if present, into an array of Range objects. Returns nil if the header is missing or syntactically invalid. Returns an empty array if none of the ranges are satisfiable.
Modified version of stdlib time.rb Time#rfc2822 to use ’%d-%b-%Y’ instead of ’% %b %Y’. It assumes that the time is in GMT to comply to the RFC 2109.
NOTE: I‘m not sure the RFC says it requires GMT, but is ambigous enough that I‘m certain someone implemented only that option. Do not use %a and %b from Time.strptime, it would use localized names for weekday and month.
