+// 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.
