This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
CACHING-7 is a warning returned when a page that returns a Last-Modified HTTP header fails to return a 304 or a different Last-Modified HTTP header when requested a second time. The warning is systematically returned whenever a Last-Modified or an ETag HTTP header is used, as mentioned in: http://lists.w3.org/Archives/Public/public-mobileok-checker/2009Nov/0000.html
HttpResourceRetriever updated to take the additional HTTP headers provided to the method into account. This had been incorrectly dropped during the library re-factoring.
