| 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. | |
