michael@0	1	//
michael@0	2	// This script emulates the test called "Freshness"
michael@0	3	// by Mark Nottingham, located at
michael@0	4	//
michael@0	5	// http://mnot.net/javascript/xmlhttprequest/cache.html
michael@0	6	//
michael@0	7	// The issue with Mr. Nottinghams page is that the server
michael@0	8	// always seems to send an Expires-header in the response,
michael@0	9	// breaking the finer details of the test. This script has
michael@0	10	// full control of response-headers, however, and can perform
michael@0	11	// the intended testing plus some extra stuff.
michael@0	12	//
michael@0	13	// Please see RFC 2616 section 13.2.1 6th paragraph for the
michael@0	14	// definition of "explicit expiration time" being used here.
