[w3.org...] Expires: max-age: Justin
Just to clarify the way an Expires and Cache-Control 'max-age' header should be set for future visitors:
The format is an absolute date and time as defined by HTTP-date in section 3.3.1; it MUST be in RFC 1123 date format.
Indicates that the client is willing to accept a response whose age is no greater than the specified time in seconds.
