Connection: "close" — Case sensitive or not?

For compatibility with the web, the "close" connection option needs to  
be treated case insensitively. My reading of the spec gives me the  
impression that this should be a case sensitive comparison, unlike any  
other connection-token (which, as a header name, would be compared  
case insensitively).
