Test for max-age + must-revalidate

Unless you force a refresh, the box below SHOULD NOT change colors when navigating between these pages: Page 1 | Page 2

The stylesheet of this page specifies a random color for the box, and is served with:

• Cache-Control: max-age=86000, public, must-revalidate
• Expires: Sun, 05 Feb 2012 05:04:06 GMT
• Last-Modified: Thu, 09 Apr 2009 17:45:53 GMT
• ETag: "1239299153pub"

Although Last-Modified and ETag are sent, the server always returns 200 so you can see that the conditional GET took place.
