     2 // This script emulates the test called "Freshness"

     3 // by Mark Nottingham, located at

     4 //

     5 // http://mnot.net/javascript/xmlhttprequest/cache.html

     6 //

     7 // The issue with Mr. Nottinghams page is that the server

     8 // always seems to send an Expires-header in the response,

     9 // breaking the finer details of the test. This script has

    10 // full control of response-headers, however, and can perform

    11 // the intended testing plus some extra stuff.

    12 //

    13 // Please see RFC 2616 section 13.2.1 6th paragraph for the

    14 // definition of "explicit expiration time" being used here.
