           Summary: HTTP: max-age/Expires ignored if must-revalidate sent
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
               URL: http://mrclay.org/tests/mustRevalidateTest/
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: steve at mrclay.org


If the Cache-Control directive "must-revalidate" is included, Win/Safari 4b and
the latest nightly ignore the Expires header and max-age directive and send a
conditional GET each time a resource is needed.

must-revalidate defines behavior AFTER a cache becomes stale. FF3, IE8, O9.6,
Chrome and Safari 3.2.2 behave correctly, only sending a conditional GET after
the Expires time.

Ignoring max-age is a long-standing webkit bug, but now Expires is being
ignored as well.
