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