4.2.3.1

If a server varies its representation according to examination of 
received HTTP headers then it must include a Vary HTTP header indicating 
this to be the case. If, in addition to, or instead of HTTP headers, a 
server varies its representation based on other factors (e.g. source IP 
Address) then it must, in accordance with [RFC 2616 
HTTP]<http://www.w3.org/TR/2008/WD-ct-guidelines-20080801/#ref-HTTP>, 
include a Vary header containing the value '*'.

What should contain the Vary HTTP Header when a server varies its 
representation according to examination of received HTTP headers?

Proposed resolution:

Change text to read

If a server varies its representation according to examination of 
received HTTP headers then it must include a Vary HTTP header indicating 
the headers it examines in accordance with [ref].
