<title>Test Caching "max-age" For History Only</title>
</head>
<body>
<p>
This test checks that loading a subresource with "Cache-Control: max-age=0" is
cached and reused in back navigation when the page is not in the page cache.
</p>
<p>
We then test that loading the same subresource is refetched when used in
non-stale loads such as refreshes or normal navigation.
</p>
